1 News for the tz database 2 3 Release 2014e - 2014-06-12 21:53:52 -0700 4 5 Changes affecting near-future time stamps 6 7 Egypt's 2014 Ramadan-based transitions are June 26 and July 31 at 24:00. 8 (Thanks to Imed Chihi.) Guess that from 2015 on Egypt will temporarily 9 switch to standard time at 24:00 the last Thursday before Ramadan, and 10 back to DST at 00:00 the first Friday after Ramadan. 11 12 Similarly, Morocco's are June 28 at 03:00 and August 2 at 02:00. (Thanks 13 to Milamber Space Network.) Guess that from 2015 on Morocco will 14 temporarily switch to standard time at 03:00 the last Saturday before 15 Ramadan, and back to DST at 02:00 the first Saturday after Ramadan. 16 17 Changes affecting past time stamps 18 19 The abbreviation "MSM" (Moscow Midsummer Time) is now used instead of 20 "MSD" for Moscow's double daylight time in summer 1921. Also, a typo 21 "VLASST" has been repaired to be "VLAST" for Vladivostok summer time 22 in 1991. (Thanks to Hank W. for reporting the problems.) 23 24 Changes affecting commentary 25 26 tz-link.htm now cites RFC 7265 for jCal, mentions PTP and the 27 draft CalDAV extension, updates URLs for TSP, TZInfo, IATA, and 28 removes stale pointers to World Time Explorer and WORLDTIME. 29 30 31 Release 2014d - 2014-05-27 21:34:40 -0700 32 33 Changes affecting code 34 35 zic no longer generates files containing time stamps before the Big Bang. 36 This works around GNOME bug 730332 37 <https://bugzilla.gnome.org/show_bug.cgi?id=730332>. 38 (Thanks to Leonardo Chiquitto for reporting the bug, and to 39 Arthur David Olson and James Cloos for suggesting improvements to the fix.) 40 41 Changes affecting documentation 42 43 tz-link.htm now mentions GNOME. 44 45 46 Release 2014c - 2014-05-13 07:44:13 -0700 47 48 Changes affecting near-future time stamps 49 50 Egypt observes DST starting 2014-05-15 at 24:00. 51 (Thanks to Ahmad El-Dardiry and Gunther Vermier.) 52 Details have not been announced, except that DST will not be observed 53 during Ramadan. Guess that DST will stop during the same Ramadan dates as 54 Morocco, and that Egypt's future spring and fall transitions will be the 55 same as 2010 when it last observed DST, namely April's last Friday at 56 00:00 to September's last Thursday at 23:00 standard time. Also, guess 57 that Ramadan transitions will be at 00:00 standard time. 58 59 Changes affecting code 60 61 zic now generates transitions for minimum time values, eliminating guesswork 62 when handling low-valued time stamps. (Thanks to Arthur David Olson.) 63 64 Port to Cygwin sans glibc. (Thanks to Arthur David Olson.) 65 66 Changes affecting commentary and documentation 67 68 Remove now-confusing comment about Jordan. (Thanks to Oleksii Nochovnyi.) 69 70 71 Release 2014b - 2014-03-24 21:28:50 -0700 72 73 Changes affecting near-future time stamps 74 75 Crimea switches to Moscow time on 2014-03-30 at 02:00 local time. 76 (Thanks to Alexander Krivenyshev.) Move its zone.tab entry from UA to RU. 77 78 New entry for Troll station, Antarctica. (Thanks to Paul-Inge Flakstad and 79 Bengt-Inge Larsson.) This is currently an approximation; a better version 80 will require the zic and localtime fixes mentioned below, and the plan is 81 to wait for a while until at least the zic fixes propagate. 82 83 Changes affecting code 84 85 'zic' and 'localtime' no longer reject locations needing four transitions 86 per year for the forseeable future. (Thanks to Andrew Main (Zefram).) 87 Also, 'zic' avoids some unlikely failures due to integer overflow. 88 89 Changes affecting build procedure 90 91 'make check' now detects Rule lines defined but never used. 92 The NZAQ rules, an instance of this problem, have been removed. 93 94 Changes affecting commentary and documentation 95 96 Fix Tuesday/Thursday typo in description of time in Israel. 97 (Thanks to Bert Katz via Pavel Kharitonov and Mike Frysinger.) 98 99 Microsoft Windows 8.1 doesn't support tz database names. (Thanks 100 to Donald MacQueen.) Instead, the Microsoft Windows Store app 101 library supports them. 102 103 Add comments about Johnston Island time in the 1960s. 104 (Thanks to Lyle McElhaney.) 105 106 Morocco's 2014 DST start will be as predicted. 107 (Thanks to Sebastien Willemijns.) 108 109 110 Release 2014a - 2014-03-07 23:30:29 -0800 111 112 Changes affecting near-future time stamps 113 114 Turkey begins DST on 2014-03-31, not 03-30. (Thanks to Faruk Pasin for 115 the heads-up, and to Tim Parenti for simplifying the update.) 116 117 Changes affecting past time stamps 118 119 Fiji ended DST on 2014-01-19 at 02:00, not the previously-scheduled 03:00. 120 (Thanks to Steffen Thorsen.) 121 122 Ukraine switched from Moscow to Eastern European time on 1990-07-01 123 (not 1992-01-01), and observed DST during the entire next winter. 124 (Thanks to Vladimir in Moscow via Alois Treindl.) 125 126 In 1988 Israel observed DST from 04-10 to 09-04, not 04-09 to 09-03. 127 (Thanks to Avigdor Finkelstein.) 128 129 Changes affecting code 130 131 A uninitialized-storage bug in 'localtime' has been fixed. 132 (Thanks to Logan Chien.) 133 134 Changes affecting the build procedure 135 136 The settings for 'make check_web' now default to Ubuntu 13.10. 137 138 Changes affecting commentary and documentation 139 140 The boundary of the US Pacific time zone is given more accurately. 141 (Thanks to Alan Mintz.) 142 143 Chile's 2014 DST will be as predicted. (Thanks to Jose Miguel Garrido.) 144 145 Paraguay's 2014 DST will be as predicted. (Thanks to Carlos Raul Perasso.) 146 147 Better descriptions of countries with same time zone history as 148 Trinidad and Tobago since 1970. (Thanks to Alan Barrett for suggestion.) 149 150 Several changes affect tz-link.htm, the main web page. 151 152 Mention Time.is (thanks to Even Scharning) and WX-now (thanks to 153 David Braverman). 154 155 Mention xCal (Internet RFC 6321) and jCal. 156 157 Microsoft has some support for tz database names. 158 159 CLDR data is available in both XML and JSON form. 160 161 Mention Maggiolo's map of solar vs standard time. 162 (Thanks to Arthur David Olson.) 163 164 Mention TZ4Net. (Thanks to Matt Johnson.) 165 166 Mention the timezone-olson Haskell package. 167 168 Mention zeitverschiebung.net. (Thanks to Martin Jaeger.) 169 170 Remove moribund links to daylight-savings-time.info and to 171 Simple Timer + Clocks. 172 173 Update two links. (Thanks to Oscar van Vlijmen.) 174 175 Fix some formatting glitches, e.g., remove random newlines from 176 abbr elements' title attributes. 177 178 179 Release 2013i - 2013-12-17 07:25:23 -0800 180 181 Changes affecting near-future time stamps: 182 183 Jordan switches back to standard time at 00:00 on December 20, 2013. 184 The 2006-2011 transition schedule is planned to resume in 2014. 185 (Thanks to Steffen Thorsen.) 186 187 Changes affecting past time stamps: 188 189 In 2004, Cuba began DST on March 28, not April 4. 190 (Thanks to Steffen Thorsen.) 191 192 Changes affecting code 193 194 The compile-time flag NOSOLAR has been removed, as nowadays the 195 benefit of slightly shrinking runtime table size is outweighed by the 196 cost of disallowing potential future updates that exceed old limits. 197 198 Changes affecting documentation and commentary 199 200 The files solar87, solar88, and solar89 are no longer distributed. 201 They were a negative experiment -- that is, a demonstration that 202 tz data can represent solar time only with some difficulty and error. 203 Their presence in the distribution caused confusion, as Riyadh 204 civil time was generally not solar time in those years. 205 206 tz-link.htm now mentions Noda Time. (Thanks to Matt Johnson.) 207 208 209 Release 2013h - 2013-10-25 15:32:32 -0700 210 211 Changes affecting current and future time stamps: 212 213 Libya has switched its time zone back to UTC+2 without DST, 214 instead of UTC+1 with DST. (Thanks to Even Scharning.) 215 216 Western Sahara (Africa/El_Aaiun) uses Morocco's DST rules. 217 (Thanks to Gwillim Law.) 218 219 Changes affecting future time stamps: 220 221 Acre and (we guess) western Amazonas will switch from UTC-4 to UTC-5 222 on 2013-11-10. This affects America/Rio_Branco and America/Eirunepe. 223 (Thanks to Steffen Thorsen.) 224 225 Add entries for DST transitions in Morocco in the year 2038. 226 This avoids some year-2038 glitches introduced in 2013g. 227 (Thanks to Yoshito Umaoka for reporting the problem.) 228 229 Changes affecting API 230 231 The 'tzselect' command no longer requires the 'select' command, 232 and should now work with /bin/sh on more platforms. It also works 233 around a bug in BusyBox awk before version 1.21.0. (Thanks to 234 Patrick 'P. J.' McDermott.) 235 236 Changes affecting code 237 238 Fix localtime overflow bugs with 32-bit unsigned time_t. 239 240 zdump no longer assumes sscanf returns maximal values on overflow. 241 242 Changes affecting the build procedure 243 244 The builder can specify which programs to use, if any, instead of 245 'ar' and 'ranlib', and libtz.a is now built locally before being 246 installed. (Thanks to Michael Forney.) 247 248 A dependency typo in the 'zdump' rule has been fixed. 249 (Thanks to Andrew Paprocki.) 250 251 The Makefile has been simplified by assuming that 'mkdir -p' and 'cp -f' 252 work as specified by POSIX.2-1992 or later; this is portable nowadays. 253 254 'make clean' no longer removes 'leapseconds', since it's 255 host-independent and is part of the distribution. 256 257 The unused makefile macros TZCSRCS, TZDSRCS, DATESRCS have been removed. 258 259 Changes affecting documentation and commentary 260 261 tz-link.htm now mentions TC TIMEZONE's draft timezone service protocol 262 (thanks to Mike Douglass) and TimezoneJS.Date (thanks to Jim Fehrle). 263 264 Update URLs in tz-link page. Add URLs for Microsoft Windows, since 265 8.1 introduces tz support. Remove URLs for Tru64 and UnixWare (no 266 longer maintained) and for old advisories. SOFA now does C. 267 268 Release 2013g - 2013-09-30 21:08:26 -0700 269 270 Changes affecting current and near-future time stamps 271 272 Morocco now observes DST from the last Sunday in March to the last 273 Sunday in October, not April to September respectively. (Thanks 274 to Steffen Thorsen.) 275 276 Changes affecting 'zic' 277 278 'zic' now runs on platforms that lack both hard links and symlinks. 279 (Thanks to Theo Veenker for reporting the problem, for MinGW.) 280 Also, fix some bugs on platforms that lack hard links but have symlinks. 281 282 'zic -v' again warns that Asia/Tehran has no POSIX environment variable 283 to predict the far future, fixing a bug introduced in 2013e. 284 285 Changes affecting the build procedure 286 287 The 'leapseconds' file is again put into the tzdata tarball. 288 Also, 'leapseconds.awk', so tzdata is self-contained. (Thanks to 289 Matt Burgess and Ian Abbott.) The timestamps of these and other 290 dependent files in tarballs are adjusted more consistently. 291 292 Changes affecting documentation and commentary 293 294 The README file is now part of the data tarball as well as the code. 295 It now states that files are public domain unless otherwise specified. 296 (Thanks to Andrew Main (Zefram) for asking for clarifications.) 297 Its details about the 1989 release moved to a place of honor near 298 the end of NEWS. 299 300 301 Release 2013f - 2013-09-24 23:37:36 -0700 302 303 Changes affecting near-future time stamps 304 305 Tocantins will very likely not observe DST starting this spring. 306 (Thanks to Steffen Thorsen.) 307 308 Jordan will likely stay at UTC+3 indefinitely, and will not fall 309 back this fall. 310 311 Palestine will fall back at 00:00, not 01:00. (Thanks to Steffen Thorsen.) 312 313 Changes affecting API 314 315 The types of the global variables 'timezone' and 'altzone' (if present) 316 have been changed back to 'long'. This is required for 'timezone' 317 by POSIX, and for 'altzone' by common practice, e.g., Solaris 11. 318 These variables were originally 'long' in the tz code, but were 319 mistakenly changed to 'time_t' in 1987; nobody reported the 320 incompatibility until now. The difference matters on x32, where 321 'long' is 32 bits and 'time_t' is 64. (Thanks to Elliott Hughes.) 322 323 Changes affecting the build procedure 324 325 Avoid long strings in leapseconds.awk to work around a mawk bug. 326 (Thanks to Cyril Baurand.) 327 328 Changes affecting documentation and commentary 329 330 New file 'NEWS' that contains release notes like this one. 331 332 Paraguay's law does not specify DST transition time; 00:00 is customary. 333 (Thanks to Waldemar Villamayor-Venialbo.) 334 335 Minor capitalization fixes. 336 337 Changes affecting version-control only 338 339 The experimental github repository now contains annotated and 340 signed tags for recent releases, e.g., '2013e' for Release 2013e. 341 Releases are tagged starting with 2012e; earlier releases were 342 done differently, and tags would either not have a simple name or 343 not exactly match what was released. 344 345 'make set-timestamps' is now simpler and a bit more portable. 346 347 348 Release 2013e - 2013-09-19 23:50:04 -0700 349 350 Changes affecting near-future time stamps 351 352 This year Fiji will start DST on October 27, not October 20. 353 (Thanks to David Wheeler for the heads-up.) For now, guess that 354 Fiji will continue to spring forward the Sunday before the fourth 355 Monday in October. 356 357 Changes affecting current and future time zone abbreviations 358 359 Use WIB/WITA/WIT rather than WIT/CIT/EIT for alphabetic Indonesian 360 time zone abbreviations since 1932. (Thanks to George Ziegler, 361 Priyadi Iman Nurcahyo, Zakaria, Jason Grimes, Martin Pitt, and 362 Benny Lin.) This affects Asia/Dili, Asia/Jakarta, Asia/Jayapura, 363 Asia/Makassar, and Asia/Pontianak. 364 365 Use ART (UTC-3, standard time), rather than WARST (also UTC-3, but 366 daylight saving time) for San Luis, Argentina since 2009. 367 368 Changes affecting Godthab time stamps after 2037 if version mismatch 369 370 Allow POSIX-like TZ strings where the transition time's hour can 371 range from -167 through 167, instead of the POSIX-required 0 372 through 24. E.g., TZ='FJT-12FJST,M10.3.1/146,M1.3.4/75' for the 373 new Fiji rules. This is a more-compact way to represent 374 far-future time stamps for America/Godthab, America/Santiago, 375 Antarctica/Palmer, Asia/Gaza, Asia/Hebron, Asia/Jerusalem, 376 Pacific/Easter, and Pacific/Fiji. Other zones are unaffected by 377 this change. (Derived from a suggestion by Arthur David Olson.) 378 379 Allow POSIX-like TZ strings where daylight saving time is in 380 effect all year. E.g., TZ='WART4WARST,J1/0,J365/25' for Western 381 Argentina Summer Time all year. This supports a more-compact way 382 to represent the 2013d data for America/Argentina/San_Luis. 383 Because of the change for San Luis noted above this change does not 384 affect the current data. (Thanks to Andrew Main (Zefram) for 385 suggestions that improved this change.) 386 387 Where these two TZ changes take effect, there is a minor extension 388 to the tz file format in that it allows new values for the 389 embedded TZ-format string, and the tz file format version number 390 has therefore been increased from 2 to 3 as a precaution. 391 Version-2-based client code should continue to work as before for 392 all time stamps before 2038. Existing version-2-based client code 393 (tzcode, GNU/Linux, Solaris) has been tested on version-3-format 394 files, and typically works in practice even for time stamps after 395 2037; the only known exception is America/Godthab. 396 397 Changes affecting time stamps before 1970 398 399 Pacific/Johnston is now a link to Pacific/Honolulu. This corrects 400 some errors before 1947. 401 402 Some zones have been turned into links, when they differ from 403 existing zones only in older data that was likely invented or that 404 differs only in LMT or transition from LMT. These changes affect 405 only time stamps before 1943. The affected zones are: 406 Africa/Juba, America/Anguilla, America/Aruba, America/Dominica, 407 America/Grenada, America/Guadeloupe, America/Marigot, 408 America/Montserrat, America/St_Barthelemy, America/St_Kitts, 409 America/St_Lucia, America/St_Thomas, America/St_Vincent, 410 America/Tortola, and Europe/Vaduz. (Thanks to Alois Treindl for 411 confirming that the old Europe/Vaduz zone was wrong and the new 412 link is better for WWII-era times.) 413 414 Change Kingston Mean Time from -5:07:12 to -5:07:11. This affects 415 America/Cayman, America/Jamaica and America/Grand_Turk time stamps 416 from 1890 to 1912. 417 418 Change the UT offset of Bern Mean Time from 0:29:44 to 0:29:46. 419 This affects Europe/Zurich time stamps from 1853 to 1894. (Thanks 420 to Alois Treindl). 421 422 Change the date of the circa-1850 Zurich transition from 1849-09-12 423 to 1853-07-16, overriding Shanks with data from Messerli about 424 postal and telegraph time in Switzerland. 425 426 Changes affecting time zone abbreviations before 1970 427 428 For Asia/Jakarta, use BMT (not JMT) for mean time from 1923 to 1932, 429 as Jakarta was called Batavia back then. 430 431 Changes affecting API 432 433 The 'zic' command now outputs a dummy transition when far-future 434 data can't be summarized using a TZ string, and uses a 402-year 435 window rather than a 400-year window. For the current data, this 436 affects only the Asia/Tehran file. It does not affect any of the 437 time stamps that this file represents, so zdump outputs the same 438 information as before. (Thanks to Andrew Main (Zefram).) 439 440 The 'date' command has a new '-r' option, which lets you specify 441 the integer time to display, a la FreeBSD. 442 443 The 'tzselect' command has two new options '-c' and '-n', which lets you 444 select a zone based on latitude and longitude. 445 446 The 'zic' command's '-v' option now warns about constructs that 447 require the new version-3 binary file format. (Thanks to Arthur 448 David Olson for the suggestion.) 449 450 Support for floating-point time_t has been removed. 451 It was always dicey, and POSIX no longer requires it. 452 (Thanks to Eric Blake for suggesting to the POSIX committee to 453 remove it, and thanks to Alan Barrett, Clive D.W. Feather, Andy 454 Heninger, Arthur David Olson, and Alois Treindl, for reporting 455 bugs and elucidating some of the corners of the old floating-point 456 implementation.) 457 458 The signatures of 'offtime', 'timeoff', and 'gtime' have been 459 changed back to the old practice of using 'long' to represent UT 460 offsets. This had been inadvertently and mistakenly changed to 461 'int_fast32_t'. (Thanks to Christos Zoulos.) 462 463 The code avoids undefined behavior on integer overflow in some 464 more places, including gmtime, localtime, mktime and zdump. 465 466 Changes affecting the zdump utility 467 468 zdump now outputs "UT" when referring to Universal Time, not "UTC". 469 "UTC" does not make sense for time stamps that predate the introduction 470 of UTC, whereas "UT", a more-generic term, does. (Thanks to Steve Allen 471 for clarifying UT vs UTC.) 472 473 Data changes affecting behavior of tzselect and similar programs 474 475 Country code BQ is now called the more-common name "Caribbean Netherlands" 476 rather than the more-official "Bonaire, St Eustatius & Saba". 477 478 Remove from zone.tab the names America/Montreal, America/Shiprock, 479 and Antarctica/South_Pole, as they are equivalent to existing 480 same-country-code zones for post-1970 time stamps. The data for 481 these names are unchanged, so the names continue to work as before. 482 483 Changes affecting code internals 484 485 zic -c now runs way faster on 64-bit hosts when given large numbers. 486 487 zic now uses vfprintf to avoid allocating and freeing some memory. 488 489 tzselect now computes the list of continents from the data, 490 rather than have it hard-coded. 491 492 Minor changes pacify GCC 4.7.3 and GCC 4.8.1. 493 494 Changes affecting the build procedure 495 496 The 'leapseconds' file is now generated automatically from a 497 new file 'leap-seconds.list', which is a copy of 498 <ftp://time.nist.gov/pub/leap-seconds.list>. 499 A new source file 'leapseconds.awk' implements this. 500 The goal is simplification of the future maintenance of 'leapseconds'. 501 502 When building the 'posix' or 'right' subdirectories, if the 503 subdirectory would be a copy of the default subdirectory, it is 504 now made a symbolic link if that is supported. This saves about 505 2 MB of file system space. 506 507 The links America/Shiprock and Antarctica/South_Pole have been 508 moved to the 'backward' file. This affects only nondefault builds 509 that omit 'backward'. 510 511 Changes affecting version-control only 512 513 .gitignore now ignores 'date'. 514 515 Changes affecting documentation and commentary 516 517 Changes to the 'tzfile' man page 518 519 It now mentions that the binary file format may be extended in 520 future versions by appending data. 521 522 It now refers to the 'zdump' and 'zic' man pages. 523 524 Changes to the 'zic' man page 525 526 It lists conditions that elicit a warning with '-v'. 527 528 It says that the behavior is unspecified when duplicate names 529 are given, or if the source of one link is the target of another. 530 531 Its examples are updated to match the latest data. 532 533 The definition of white space has been clarified slightly. 534 (Thanks to Michael Deckers.) 535 536 Changes to the 'Theory' file 537 538 There is a new section about the accuracy of the tz database, 539 describing the many ways that errors can creep in, and 540 explaining why so many of the pre-1970 time stamps are wrong or 541 misleading (thanks to Steve Allen, Lester Caine, and Garrett 542 Wollman for discussions that contributed to this). 543 544 The 'Theory' file describes LMT better (this follows a 545 suggestion by Guy Harris). 546 547 It refers to the 2013 edition of POSIX rather than the 2004 edition. 548 549 It's mentioned that excluding 'backward' should not affect the 550 other data, and it suggests at least one zone.tab name per 551 inhabited country (thanks to Stephen Colebourne). 552 553 Some longstanding restrictions on names are documented, e.g., 554 'America/New_York' precludes 'America/New_York/Bronx'. 555 556 It gives more reasons for the 1970 cutoff. 557 558 It now mentions which time_t variants are supported, such as 559 signed integer time_t. (Thanks to Paul Goyette for reporting 560 typos in an experimental version of this change.) 561 562 (Thanks to Philip Newton for correcting typos in these changes.) 563 564 Documentation and commentary is more careful to distinguish UT in 565 general from UTC in particular. (Thanks to Steve Allen.) 566 567 Add a better source for the Zurich 1894 transition. 568 (Thanks to Pierre-Yves Berger.) 569 570 Update shapefile citations in tz-link.htm. (Thanks to Guy Harris.) 571 572 573 Release 2013d - 2013-07-05 07:38:01 -0700 574 575 Changes affecting future time stamps: 576 577 Morocco's midsummer transitions this year are July 7 and August 10, 578 not July 9 and August 8. (Thanks to Andrew Paprocki.) 579 580 Israel now falls back on the last Sunday of October. 581 (Thanks to Ephraim Silverberg.) 582 583 Changes affecting past time stamps: 584 585 Specify Jerusalem's location more precisely; this changes the pre-1880 586 times by 2 s. 587 588 Changing affecting metadata only: 589 590 Fix typos in the entries for country codes BQ and SX. 591 592 Changes affecting code: 593 594 Rework the code to fix a bug with handling Australia/Macquarie on 595 32-bit hosts (thanks to Arthur David Olson). 596 597 Port to platforms like NetBSD, where time_t can be wider than long. 598 599 Add support for testing time_t types other than the system's. 600 Run 'make check_time_t_alternatives' to try this out. 601 Currently, the tests fail for unsigned time_t; 602 this should get fixed at some point. 603 604 Changes affecting documentation and commentary: 605 606 Deemphasize the significance of national borders. 607 608 Update the zdump man page. 609 610 Remove obsolete NOID comment (thanks to Denis Excoffier). 611 612 Update several URLs and comments in the web pages. 613 614 Spelling fixes (thanks to Kevin Lyda and Jonathan Leffler). 615 616 Update URL for CLDR Zone->Tzid table (thanks to Yoshito Umaoka). 617 618 619 Release 2013c - 2013-04-19 16:17:40 -0700 620 621 Changes affecting current and future time stamps: 622 623 Palestine observed DST starting March 29, 2013. (Thanks to 624 Steffen Thorsen.) From 2013 on, Gaza and Hebron both observe DST, 625 with the predicted rules being the last Thursday in March at 24:00 626 to the first Friday on or after September 21 at 01:00. 627 628 Assume that the recent change to Paraguay's DST rules is permanent, 629 by moving the end of DST to the 4th Sunday in March every year. 630 (Thanks to Carlos Raul Perasso.) 631 632 Changes affecting past time stamps: 633 634 Fix some historical data for Palestine to agree with that of 635 timeanddate.com, as follows: 636 637 The spring 2008 change in Gaza and Hebron was on 00:00 Mar 28, not 638 00:00 Apr 1. 639 640 The fall 2009 change in Gaza and Hebron on Sep 4 was at 01:00, not 641 02:00. 642 643 The spring 2010 change in Hebron was 00:00 Mar 26, not 00:01 Mar 27. 644 645 The spring 2011 change in Gaza was 00:01 Apr 1, not 12:01 Apr 2. 646 647 The spring 2011 change in Hebron on Apr 1 was at 00:01, not 12:01. 648 649 The fall 2011 change in Hebron on Sep 30 was at 00:00, not 03:00. 650 651 Fix times of habitation for Macquarie to agree with the Tasmania 652 Parks & Wildlife Service history, which indicates that permanent 653 habitation was 1899-1919 and 1948 on. 654 655 Changing affecting metadata only: 656 657 Macquarie Island is politically part of Australia, not Antarctica. 658 (Thanks to Tobias Conradi.) 659 660 Sort Macquarie more-consistently with other parts of Australia. 661 (Thanks to Tim Parenti.) 662 663 664 Release 2013b - 2013-03-10 22:33:40 -0700 665 666 Changes affecting current and future time stamps: 667 668 Haiti uses US daylight-saving rules this year, and presumably future years. 669 This changes time stamps starting today. (Thanks to Steffen Thorsen.) 670 671 Paraguay will end DST on March 24 this year. 672 (Thanks to Steffen Thorsen.) For now, assume it's just this year. 673 674 Morocco does not observe DST during Ramadan; 675 try to predict Ramadan in Morocco as best we can. 676 (Thanks to Erik Homoet for the heads-up.) 677 678 Changes affecting commentary: 679 680 Update URLs in tz-link page. Add URLs for webOS, BB10, iOS. 681 Update URL for Solaris. Mention Internet RFC 6557. 682 Update Internet RFCs 2445->5545, 2822->5322. 683 Switch from FTP to HTTP for Internet RFCs. 684 685 686 Release 2013a - 2013-02-27 09:20:35 -0800 687 688 Change affecting binary data format: 689 690 The zone offset at the end of version-2-format zone files is now 691 allowed to be 24:00, as per POSIX.1-2008. (Thanks to Arthor David Olson.) 692 693 Changes affecting current and future time stamps: 694 695 Chile's 2013 rules, and we guess rules for 2014 and later, will be 696 the same as 2012, namely Apr Sun>=23 03:00 UTC to Sep Sun>=2 04:00 UTC. 697 (Thanks to Steffen Thorsen and Robert Elz.) 698 699 New Zones Asia/Khandyga, Asia/Ust-Nera, Europe/Busingen. 700 (Thanks to Tobias Conradi and Arthur David Olson.) 701 702 Many changes affect historical time stamps before 1940. 703 These were deduced from: Milne J. Civil time. Geogr J. 1899 704 Feb;13(2):173-94 <http://www.jstor.org/stable/1774359>. 705 706 Changes affecting the code: 707 708 Fix zic bug that mishandled Egypt's 2010 changes (this also affected 709 the data). (Thanks to Arthur David Olson.) 710 711 Fix localtime bug when time_t is unsigned and data files were generated 712 by a signed time_t system. (Thanks to Doug Bailey for reporting and 713 to Arthur David Olson for fixing.) 714 715 Allow the email address for bug reports to be set by the packager. 716 The default is tz (a] iana.org, as before. (Thanks to Joseph S. Myers.) 717 718 Update HTML checking to be compatible with Ubuntu 12.10. 719 720 Check that files are a safe subset of ASCII. At some point we may 721 relax this requirement to a safe subset of UTF-8. Without the 722 check, some non-UTF-8 encodings were leaking into the distribution. 723 724 Commentary changes: 725 726 Restore a comment about copyright notices that was inadvertently deleted. 727 (Thanks to Arthur David Olson.) 728 729 Improve the commentary about which districts observe what times 730 in Russia. (Thanks to Oscar van Vlijmen and Arthur David Olson). 731 732 Add web page links to tz.js. 733 734 Add "Run by the Monkeys" to tz-art. (Thanks to Arthur David Olson.) 735 736 737 Release 2012j - 2012-11-12 18:34:49 -0800 738 739 Libya moved to CET this weekend, but with DST planned next year. 740 (Thanks to Even Scharning, Steffen Thorsen, and Tim Parenti.) 741 742 Signatures now have the extension .asc, not .sign, as that's more 743 standard. (Thanks to Phil Pennock.) 744 745 The output of 'zdump --version', and of 'zic --version', now 746 uses a format that is more typical for --version. 747 (Thanks to Joseph S. Myers.) 748 749 The output of 'tzselect --help', 'zdump --help', and 'zic --help' 750 now uses tz (a] iana.org rather than the old elsie address. 751 752 zic -v now complains about abbreviations that are less than 3 753 or more than 6 characters, as per Posix. Formerly, it checked 754 for abbreviations that were more than 3. 755 756 'make public' no longer puts its temporary directory under /tmp, 757 and uses the just-built zic rather than the system zic. 758 759 Various fixes to documentation and commentary. 760 761 762 Release 2012i - 2012-11-03 12:57:09 -0700 763 764 Cuba switches from DST tomorrow at 01:00. (Thanks to Steffen Thorsen.) 765 766 Linker flags can now be specified via LDFLAGS. 767 AWK now defaults to 'awk', not 'nawk'. 768 The shell in tzselect now defaults to /bin/bash, but this can 769 be overridden by specifying KSHELL. 770 The main web page now mentions the unofficial github repository. 771 (Thanks to Mike Frysinger.) 772 773 Tarball signatures can now be built by running 'make signatures'. 774 There are also new makefile rules 'tarballs', 'check_public', and 775 separate makefile rules for each tarball and signature file. 776 A few makefile rules are now more portable to strict POSIX. 777 778 The main web page now lists the canonical IANA URL. 779 780 781 Release 2012h - 2012-10-26 22:49:10 -0700 782 783 Bahia no longer has DST. (Thanks to Kelley Cook.) 784 785 Tocantins has DST. (Thanks to Rodrigo Severo.) 786 787 Israel has new DST rules next year. (Thanks to Ephraim Silverberg.) 788 789 Jordan stays on DST this winter. (Thanks to Steffen Thorsen.) 790 791 Web page updates. 792 793 More C modernization, except that at Arthur David Olson's suggestion 794 the instances of 'register' were kept. 795 796 797 Release 2012g - 2012-10-17 20:59:45 -0700 798 799 Samoa fall 2012 and later. (Thanks to Nicholas Pereira and Robert Elz.) 800 801 Palestine fall 2012. (Thanks to Steffen Thorsen.) 802 803 Assume C89. 804 805 To attack the version-number problem, this release ships the file 806 'Makefile' (which contains the release number) in both the tzcode and 807 the tzdata tarballs. The two Makefiles are identical, and should be 808 identical in any matching pair of tarballs, so it shouldn't matter 809 which order you extract the tarballs. Perhaps we can come up with a 810 better version-number scheme at some point; this scheme does have the 811 virtue of not adding more files. 812 813 814 Release 2012f - 2012-09-12 23:17:03 -0700 815 816 * australasia (Pacific/Fiji): Fiji DST is October 21 through January 817 20 this year. (Thanks to Steffen Thorsen.) 818 819 820 Release 2012e - 2012-08-02 20:44:55 -0700 821 822 * australasia (Pacific/Fakaofo): Tokelau is UTC+13, not UTC+14. 823 (Thanks to Steffen Thorsen.) 824 825 * Use a single version number for both code and data. 826 827 * .gitignore: New file. 828 829 * Remove trailing white space. 830 831 832 Release code2012c-data2012d - 2012-07-19 16:35:33 -0700 833 834 Changes for Morocco's time stamps, which take effect in a couple of 835 hours, along with infrastructure changes to accommodate how the tz 836 code and data are released on IANA. 837 838 839 Release data2012c - 2012-03-27 12:17:25 -0400 840 841 africa 842 Summer time changes for Morocco (to start late April 2012) 843 844 asia 845 Changes for 2012 for Gaza & the West Bank (Hebron) and Syria 846 847 northamerica 848 Haiti following US/Canada rules for 2012 (and we're assuming, 849 for now anyway, for the future). 850 851 852 Release 2012b - 2012-03-02 12:29:15 +0700 853 854 There is just one change to tzcode2012b (compared with 2012a): 855 the Makefile that was accidentally included with 2012a has been 856 replaced with the version that should have been there, which is 857 identical with the previous version (from tzcode2011i). 858 859 There are just two changes in tzdata2012b compared with 2012a. 860 861 Most significantly, summer time in Cuba has been delayed 3 weeks 862 (now starts April 1 rather than March 11). Since Mar 11 (the old start 863 date, as listed in 2012a) is just a little over a week away, this 864 change is urgent. 865 866 Less importantly, an excess tab in one of the changes in zone.tab 867 in 2012a has been removed. 868 869 870 Release 2012a - 2012-03-01 18:28:10 +0700 871 872 The changes in tzcode2012a (compared to the previous version, 2011i) 873 are entirely to the README and tz-art.htm and tz-link.htm files, if 874 none of those concern you, you can ignore the code update. The changes 875 reflect the changed addresses for the mailing list and the code and 876 data distribution points & methods (and a link to DateTime::TimeZone::Tzfile 877 has been added to tz-link.htm). 878 879 In tzdata2012a (compared to the previous release, which was 2011n) 880 the major changes are: 881 Chile 2011/2012 and 2012/2013 summer time date adjustments. 882 Falkland Islands onto permanent summer time (we're assuming for the 883 foreseeable future, though 2012 is all we're fairly certain of.) 884 Armenia has abolished Summer Time. 885 Tokelau jumped the International Date Line back last December 886 (just the same as their near neighbour, Samoa). 887 America/Creston is a new zone for a small area of British Columbia 888 There will be a leapsecond 2012-06-30 23:59:60 UTC. 889 890 Other minor changes are: 891 Corrections to 1918 Canadian summer time end dates. 892 Updated URL for UK timezone history (in comments) 893 A few typos in Le Corre's list of free French place names (comments) 894 895 896 Release data2011n - 2011-10-30 14:57:54 +0700 897 898 There are three changes of note - most urgently, Cuba (America/Havana) 899 has extended summer time by two weeks, now to end on Nov 13, rather than 900 the (already past) Oct 30. Second, the Pridnestrovian Moldavian Republic 901 (Europe/Tiraspol) decided not to split from the rest of Moldova after 902 all, and consequently that zone has been removed (again) and reinstated 903 in the "backward" file as a link to Europe/Chisinau. And third, the 904 end date for Fiji's summer time this summer was moved forward from the 905 earlier planned Feb 26, to Jan 22. 906 907 Apart from that, Moldova (MD) returns to a single entry in zone.tab 908 (and the incorrect syntax that was in the 2011m version of that file 909 is so fixed - it would have been fixed in a different way had this 910 change not happened - that's the "missing" sccs version id). 911 912 913 Release data2011m - 2011-10-24 21:42:16 +0700 914 915 In particular, the typos in comments in the data (2011-11-17 should have 916 been 2011-10-17 as Alan Barrett noted, and spelling of Tiraspol that 917 Tim Parenti noted) have been fixed, and the change for Ukraine has been 918 made in all 4 Ukrainian zones, rather than just Kiev (again, thanks to 919 Tim Parenti, and also Denys Gavrysh) 920 921 In addition, I added Europe/Tiraspol to zone.tab. 922 923 This time, all the files have new version numbers... (including the files 924 otherwise unchanged in 2011m that were changed in 2011l but didn't get new 925 version numbers there...) 926 927 928 Release data2011l - 2011-10-10 11:15:43 +0700 929 930 There are just 2 changes that cause different generated tzdata files from 931 zic, to Asia/Hebron and Pacific/Fiji - the possible change for Bahia, Brazil 932 is included, but commented out. Compared with the diff I sent out last week, 933 this version also includes attributions for the sources for the changes 934 (in much the same format as ado used, but the html tags have not been 935 checked, verified, or used in any way at all, so if there are errors there, 936 please let me know.) 937 938 939 Release data2011k -

The approach 2091 has been to make zic a bit smarter about figuring out what time zone 2092 abbreviations apply just after the time specified in the "UNTIL" part 2093 of a zone line. Putting the smarts in zic means avoiding having 2094 transition times show up in both "Zone" lines and "Rule" lines, which 2095 in turn avoids multiple transition time entries in time zone files. 2096 (This also makes the zic input files such as "europe" a bit shorter and 2097 should ease maintenance.) 2098 2099 2100 Release data96f - 1996-04-19 19:20:03 -0000 2101 [tzdata96f.tar.gz is missing!] 2102 2103 The only changes are to the "northamerica" file; the time zone 2104 abbreviation for Denver is corrected to MST (and MDT), and the 2105 comments for Mexico have been updated. 2106 2107 2108 Release data96e - 1996-03-19 17:37:26 -0500 2109 2110 Proposals by Paul Eggert, in particular the Portugal change that 2111 comes into play at the end of this month. 2112 2113 2114 Release data96d - 1996-03-18 20:49:39 -0500 2115 2116 [not summarized] 2117 2118 2119 Release code96e - 1996-02-29 15:43:27 -0000 2120 [tzcode96e.tar.gz is missing!] 2121 2122 internationalization changes and the fix to the documentation for strftime 2123 2124 2125 Release code96d-data96c - 1996-02-12 11:05:27 -0500 2126 2127 The "code" file simply updates Bob Kridle's electronic address. 2128 2129 The "data" file updates rules for Mexico. 2130 2131 2132 Release data96b - 1996-01-27 15:44:42 -0500 2133 2134 Kiribati change 2135 2136 2137 Release code96c - 1996-01-16 16:58:15-0500 2138 2139 leap-year streamlining and binary-search changes 2140 2141 fix to newctime.3 2142 2143 2144 Release code96b - 1996-01-10 20:42:39 -0500 2145 2146 fixes and enhancements from Paul Eggert, including code that 2147 emulates the behavior of recent versions of the SunOS "date" 2148 command. 2149 2150 2151 Release 96a - 1996-01-06 09:08:24 -0500 2152 2153 Israel updates 2154 2155 fixes to strftime.c for correct ISO 8601 week number generation, 2156 plus support for two new formats ('G' and 'g') to give ISO 8601 year 2157 numbers (which are not necessarily the same as calendar year numbers) 2158 2159 2160 Release code95i-data95m - 1995-12-21 12:46:47 -0500 2161 2162 The latest revisions from Paul Eggert are included, the usno1995 2163 file has been updated, and a new file ("WWW") covering useful URLs 2164 has been added. 2165 2166 2167 Release code95h-data95l - 1995-12-19 18:10:12 -0500 2168 2169 A simplification of a macro definition, a change to data for Sudan, 2170 and (for last minute shoppers) notes in the "Music" file on the CD 2171 "Old Man Time". 2172 2173 2174 Release code95g-data95k - 1995-10-30 10:32:47 -0500 2175 2176 (slightly reformatted) 8-bit-clean proposed patch 2177 2178 minor patch: US/Eastern -> America/New_York 2179 2180 snapshot of the USNO's latest data ("usno1995") 2181 2182 some other minor cleanups 2183 2184 2185 Release code95f-data95j - 1995-10-28 21:01:34 -0000 2186 [tzcode95f.tar.gz + tzdata95j.tar.gz are both missing!] 2187 2188 European cleanups 2189 2190 support for 64-bit time_t's 2191 2192 optimization in localtime.c 2193 2194 2195 Release code95e - 1995-10-13 13:23:57 -0400 2196 2197 the mktime change to scan from future to past when trying to find time zone 2198 offsets 2199 2200 2201 Release data95i - 1995-09-26 10:43:26 -0400 2202 2203 For Canada/Central, guess that the Sun customer's ``one week too 2204 early'' was just a approximation, and the true error is one month 2205 too early. This is consistent with the rest of Canada. 2206 2207 2208 Release data95h - 1995-09-21 11:26:48 -0400 2209 2210 latest changes from Paul Eggert 2211 2212 2213 Release code95d - 1995-09-14 11:14:45 -0400 2214 2215 the addition of a "Music" file, which documents four recorded 2216 versions of the tune "Save That Time". 2217 2218 2219 Release data95g - 1995-09-01 17:21:36 -0400 2220 2221 "yearistype" correction 2222 2223 2224 Release data95f - 1995-08-28 20:46:56 -0400 2225 2226 Paul Eggert's change to the australasia file 2227 2228 2229 Release data95e - 1995-07-08 18:02:34 -0400 2230 2231 The only change is a leap second at the end of this year. 2232 Thanks to Bradley White for forwarding news on the leap second. 2233 2234 2235 Release data95d - 1995-07-03 13:26:22 -0400 2236 2237 Paul Eggert's changes 2238 2239 2240 Release data95c - 1995-07-02 19:19:28 -0400 2241 2242 changes to "asia", "backward", "europe", and "southamerica" 2243 (read: northamericacentrics need not apply) 2244 2245 2246 Release code95c - 1995-03-13 14:00:46 -0500 2247 2248 one-line fix for sign extension problems in detzcode 2249 2250 2251 Release 95b - 1995-03-04 11:22:38 -0500 2252 2253 Minor changes in both: 2254 2255 The "code" file contains a workaround for the lack of "unistd.h" in 2256 Microsoft C++ version 7. 2257 2258 The "data" file contains a fixed "Link" for America/Shiprock. 2259 2260 2261 Release 94h - 1994-12-10 12:51:14 -0500 2262 2263 The files: 2264 2265 * incorporate the changes to "zdump" and "date" to make changes to 2266 the "TZ" environment variable permanent; 2267 2268 * incorporate the table changes by Paul Eggert; 2269 2270 * include (and document) support for universal time specifications in 2271 data files--but do not (yet) include use of this feature in the 2272 data files. 2273 2274 Think of this as "TZ Classic"--the software has been set up not to break if 2275 universal time shows up in its input, and the data has been left as is so as 2276 not to break existing implementations. 2277 2278 2279 Release data94f - 1994-08-20 12:56:09 -0400 2280 2281 (with thanks!) the latest data updates from Paul Eggert 2282 2283 2284 Release data94e - 1994-06-04 13:13:53 -0400 2285 2286 [not summarized] 2287 2288 2289 Release code94g - 1994-05-05 12:14:07 -0400 2290 2291 fix missing "optind.c" and a reference to it in the Makefile 2292 2293 2294 Release code94f - 1994-05-05 13:00:33 -0000 2295 [tzcode94f.tar.gz is missing!] 2296 2297 changes to avoid overflow in difftime, as well as changes to cope 2298 with the 52/53 challenge in strftime 2299 2300 2301 Release code94e - 1994-03-30 23:32:59 -0500 2302 2303 change for the benefit of PCTS 2304 2305 2306 Release 94d - 1994-02-24 15:42:25 -0500 2307 2308 Avoid clashes with POSIX semantics for zones such as GMT+4. 2309 2310 Some other very minor housekeeping is also present. 2311 2312 2313 Release code94c - 1994-02-10 08:52:40 -0500 2314 2315 Fix bug where mkdirs was broken unless you compile with 2316 -fwritable-strings (which is generally losing to do). 2317 2318 2319 Release 94b - 1994-02-07 10:04:33 -0500 2320 2321 work by Paul Eggert who notes: 2322 2323 I found another book of time zone histories by E W Whitman; it's not 2324 as extensive as Shanks but has a few goodies of its own. I used it 2325 to update the tables. I also fixed some more as a result of 2326 correspondence with Adam David and Peter Ilieve, and move some stray 2327 links from `europe' to `backward'. I corrected some scanning errors 2328 in usno1989. 2329 2330 As far as the code goes, I fixed zic to allow years in the range 2331 INT_MIN to INT_MAX; this fixed a few boundary conditions around 1900. 2332 And I cleaned up the zic documentation a little bit. 2333 2334 2335 Release data94a - 1994-02-03 08:58:54 -0500 2336 2337 It simply incorporates the recently announced leap second into the 2338 "leapseconds" file. 2339 2340 2341 Release 93g - 1993-11-22 17:28:27 -0500 2342 2343 Paul Eggert has provided a good deal of historic information (based 2344 on Shanks), and there are some code changes to deal with the buglets 2345 that crawled out in dealing with the new information. 2346 2347 2348 Release 93f - 1993-10-15 12:27:46 -0400 2349 2350 Paul Eggert's changes 2351 2352 2353 Release 93e - 1993-09-05 21:21:44 -0400 2354 2355 There's updated data for Israel, England, and Kwajalein; there's 2356 also an update to "zdump" to cope with Kwajalein's 24-hour jump. 2357 Thanks to Paul Eggert and Peter Ilieve for the changes. 2358 2359 2360 Release 93d - 1993-06-17 23:34:17 -0400 2361 2362 new fix and new data on Israel 2363 2364 2365 Release 93c - 1993-06-06 19:31:55 -0400 2366 2367 [not summarized] 2368 2369 2370 Release 93b - 1993-02-02 14:53:58 -0500 2371 2372 updated "leapseconds" file 2373 2374 2375 Release 93 - 1993-01-08 07:01:06 -0500 2376 2377 At kre's suggestion, the package has been split in two--a code piece 2378 (which also includes documentation) that's only of use to folks who 2379 want to recompile things and a data piece useful to anyone who can 2380 run "zic". 2381 2382 The new version has a few changes to the data files, a few 2383 portability changes, and an off-by-one fix (with thanks to 2384 Tom-Karzes at deshaw.com for providing a description and a 2385 solution). 2386 2387 2388 Release 92c - 1992-11-21 17:35:36 -0000 2389 [tz92c.tar.Z is missing!] 2390 2391 The fallout from the latest round of DST transitions. 2392 2393 There are changes for Portugal, Saskatchewan, and "Pacific-New"; 2394 there's also a change to "zic.c" that makes it portable to more systems. 2395 2396 2397 Release 92 - 1992-04-25 18:17:03 -0000 2398 [tz92.tar.Z is missing!] 2399 2400 By popular demand (well, at any rate, following a request by kre at munnari) 2401 2402 2403 The 1989 update of the time zone package featured: 2404 2405 * POSIXization (including interpretation of POSIX-style TZ environment 2406 variables, provided by Guy Harris), 2407 * ANSIfication (including versions of "mktime" and "difftime"), 2408 * SVIDulation (an "altzone" variable) 2409 * MACHination (the "gtime" function) 2410 * corrections to some time zone data (including corrections to the rules 2411 for Great Britain and New Zealand) 2412 * reference data from the United States Naval Observatory for folks who 2413 want to do additional time zones 2414 * and the 1989 data for Saudi Arabia. 2415 2416 (Since this code will be treated as "part of the implementation" in some 2417 places and as "part of the application" in others, there's no good way to 2418 name functions, such as timegm, that are not part of the proposed ANSI C 2419 standard; such functions have kept their old, underscore-free names in this 2420 update.) 2421 2422 And the "dysize" function has disappeared; it was present to allow 2423 compilation of the "date" command on old BSD systems, and a version of "date" 2424 is now provided in the package. The "date" command is not created when you 2425 "make all" since it may lack options provided by the version distributed with 2426 your operating system, or may not interact with the system in the same way 2427 the native version does. 2428 2429 Since POSIX frowns on correct leap second handling, the default behavior of 2430 the "zic" command (in the absence of a "-L" option) has been changed to omit 2431 leap second information from its output files. 2432 2433 2434 ----- 2435 Notes 2436 2437 This file contains copies of the part of each release announcement 2438 that talks about the changes in that release. The text has been 2439 adapted and reformatted for the purposes of this file. 2440 2441 Typically a release R consists of a pair of tarball files, 2442 tzcodeR.tar.gz and tzdataR.tar.gz. However, some releases (e.g., 2443 code2010a, data2012c) consist of just one or the other tarball, and a 2444 few (e.g., code2012c-data2012d) have tarballs with mixed version 2445 numbers. 2446 2447 Release time stamps are taken from the release's commit (for newer, 2448 git releases), from the newest file in the tarball (for older 2449 releases, where this info is available) or from the email announcing 2450 the release (if all else fails; these are marked with a timezone of 2451 -0000 and an "is missing!" comment). 2452 2453 Earlier versions of the code and data were not announced on the tz 2454 list and are not summarized here. 2455 2456 This file is in the public domain. 2457
