1 # Make and install tzdb code and data. 2 3 # This file is in the public domain, so clarified as of 4 # 2009-05-17 by Arthur David Olson. 5 6 # Package name for the code distribution. 7 PACKAGE= tzcode 8 9 # Version number for the distribution, overridden in the 'tarballs' rule below. 10 VERSION= unknown 11 12 # Email address for bug reports. 13 BUGEMAIL= tz@iana.org 14 15 # DATAFORM selects the data format. 16 # Available formats represent essentially the same data, albeit 17 # possibly with minor discrepancies that users are not likely to notice. 18 # To get new features and the best data right away, use: 19 # DATAFORM= vanguard 20 # To wait a while before using new features, to give downstream users 21 # time to upgrade zic (the default), use: 22 # DATAFORM= main 23 # To wait even longer for new features, use: 24 # DATAFORM= rearguard 25 DATAFORM= main 26 27 # Change the line below for your timezone (after finding the one you want in 28 # one of the $(TDATA) source files, or adding it to a source file). 29 # Alternatively, if you discover you've got the wrong timezone, you can just 30 # zic -l rightzone 31 # to correct things. 32 # Use the command 33 # make zonenames 34 # to get a list of the values you can use for LOCALTIME. 35 36 LOCALTIME= GMT 37 38 # The POSIXRULES macro controls interpretation of nonstandard and obsolete 39 # POSIX-like TZ settings like TZ='EET-2EEST' that lack DST transition rules. 40 # In the reference implementation, if you want something other than Eastern 41 # United States time as a template for handling these settings, you can 42 # change the line below (after finding the timezone you want in the 43 # one of the $(TDATA) source files, or adding it to a source file). 44 # A setting like TZ='EET-2EEST' is supposed to use the rules in the 45 # template file to determine "spring forward" and "fall back" days and 46 # times; the environment variable itself specifies UT offsets of standard and 47 # daylight saving time. 48 # Alternatively, if you discover you've got the wrong timezone, you can just 49 # zic -p rightzone 50 # to correct things. 51 # Use the command 52 # make zonenames 53 # to get a list of the values you can use for POSIXRULES. 54 # 55 # If POSIXRULES is empty, no template is installed; this is the intended 56 # future default for POSIXRULES. 57 # 58 # Nonempty POSIXRULES is obsolete and should not be relied on, because: 59 # * It does not work correctly in popular implementations such as GNU/Linux. 60 # * It does not work in the tzdb implementation for timestamps after 2037. 61 # * It is incompatible with 'zic -b slim' if POSIXRULES specifies transitions 62 # at standard time or UT rather than at local time. 63 # In short, software should avoid ruleless settings like TZ='EET-2EEST' 64 # and so should not depend on the value of POSIXRULES. 65 66 POSIXRULES= America/New_York 67 68 # Also see TZDEFRULESTRING below, which takes effect only 69 # if the time zone files cannot be accessed. 70 71 72 # Installation locations. 73 # 74 # The defaults are suitable for Debian, except that if REDO is 75 # posix_right or right_posix then files that Debian puts under 76 # /usr/share/zoneinfo/posix and /usr/share/zoneinfo/right are instead 77 # put under /usr/share/zoneinfo-posix and /usr/share/zoneinfo-leaps, 78 # respectively.

Otherwise, the functions 343 # "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the 344 # time library, and if STD_INSPIRED is also defined the functions 345 # "posix2time_z" and "time2posix_z" are added as well. 346 # The functions ending in "_z" (or "_rz") are like their unsuffixed 347 # (or suffixed-by-"_r") counterparts, except with an extra first 348 # argument of opaque type timezone_t that specifies the timezone. 349 # "tzalloc" allocates a timezone_t value, and "tzfree" frees it. 350 # 351 # If you want to allocate state structures in localtime, add 352 # -DALL_STATE 353 # to the end of the "CFLAGS=" line.
