If you want only "right" time, with values interpreted 80 # as seconds since the epoch (counting leap seconds), use 81 # REDO= right_only 82 # below.

If you want both sets of data available, with leap seconds counted 86 # normally, use 87 # REDO= right_posix 88 # below. POSIX mandates that leap seconds not be counted; for compatibility 89 # with it, use "posix_only" or "posix_right". Use POSIX time on systems with 90 # leap smearing; this can work better than unsmeared "right" time with 91 # applications that are not leap second aware, and is closer to unsmeared 92 # "right" time than unsmeared POSIX time is (e.g., 0.5 vs 1.0 s max error). 93 94 REDO= posix_right 95 96 # To install data in text form that has all the information of the binary data, 97 # (optionally incorporating leap second information), use 98 # TZDATA_TEXT= tzdata.zi leapseconds 99 # To install text data without leap second information (e.g., because 100 # REDO='posix_only'), use 101 # TZDATA_TEXT= tzdata.zi 102 # To avoid installing text data, use 103 # TZDATA_TEXT= 104 105 TZDATA_TEXT= leapseconds tzdata.zi 106 107 # For backward-compatibility links for old zone names, use 108 # BACKWARD= backward pacificnew 109 # To omit these links, use 110 # BACKWARD= 111 112 BACKWARD= backward pacificnew 113 114 # If you want out-of-scope and often-wrong data from the file 'backzone', use 115 # PACKRATDATA= backzone 116 # To omit this data, use 117 # PACKRATDATA= 118 119 PACKRATDATA= 120 121 # The name of a locale using the UTF-8 encoding, used during self-tests. 122 # The tests are skipped if the name does not appear to work on this system. 123 124 UTF8_LOCALE= en_US.utf8 125 126 # Since "." may not be in PATH... 127 128 YEARISTYPE= ./yearistype 129 130 # Non-default libraries needed to link. 131 LDLIBS= 132 133 # Add the following to the end of the "CFLAGS=" line as needed to override 134 # defaults specified in the source code.

This arranges for the functions 249 # "tzsetwall", "offtime", "timelocal", "timegm", "timeoff", 250 # "posix2time", and "time2posix" to be added to the time conversion library. 251 # "tzsetwall" is like "tzset" except that it arranges for local wall clock 252 # time (rather than the time specified in the TZ environment variable) 253 # to be used. 254 # "offtime" is like "gmtime" except that it accepts a second (long) argument 255 # that gives an offset to add to the time_t when converting it. 256 # "timelocal" is equivalent to "mktime". 257 # "timegm" is like "timelocal" except that it turns a struct tm into 258 # a time_t using UT (rather than local time as "timelocal" does). 259 # "timeoff" is like "timegm" except that it accepts a second (long) argument 260 # that gives an offset to use when converting to a time_t. 261 # "posix2time" and "time2posix" are described in an included manual page. 262 # X3J11's work does not describe any of these functions. 263 # Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0. 264 # These functions may well disappear in future releases of the time 265 # conversion package. 266 # 267 # If you don't want functions that were inspired by NetBSD, add 268 # -DNETBSD_INSPIRED=0 269 # to the end of the "CFLAGS=" line. Otherwise, the functions 270 # "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the 271 # time library, and if STD_INSPIRED is also defined the functions 272 # "posix2time_z" and "time2posix_z" are added as well. 273 # The functions ending in "_z" (or "_rz") are like their unsuffixed 274 # (or suffixed-by-"_r") counterparts, except with an extra first 275 # argument of opaque type timezone_t that specifies the time zone. 276 # "tzalloc" allocates a timezone_t value, and "tzfree" frees it. 277 # 278 # If you want to allocate state structures in localtime, add 279 # -DALL_STATE 280 # to the end of the "CFLAGS=" line. Storage is obtained by calling malloc. 281 # 282 # NIST-PCTS:151-2, Version 1.4, (1993-12-03) is a test suite put 283 # out by the National Institute of Standards and Technology 284 # which claims to test C and Posix conformance.
