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 # Rearguard users might also want "ZFLAGS = -b fat"; see below. 26 DATAFORM= main 27 28 # Change the line below for your timezone (after finding the one you want in 29 # one of the $(TDATA) source files, or adding it to a source file). 30 # Alternatively, if you discover you've got the wrong timezone, you can just 31 # 'zic -l -' to remove it, or 'zic -l rightzone' to change it. 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 # Such a setting uses the rules in a template file to determine 41 # "spring forward" and "fall back" days and times; the environment 42 # variable itself specifies UT offsets of standard and daylight saving time. 43 # 44 # If POSIXRULES is '-', no template is installed; this is the default. 45 # 46 # Any other value for POSIXRULES is obsolete and should not be relied on, as: 47 # * It does not work correctly in popular implementations such as GNU/Linux. 48 # * It does not work in the tzdb implementation for timestamps after 2037. 49 # * It is incompatible with 'zic -b slim' if POSIXRULES specifies transitions 50 # at standard time or UT rather than at local time. 51 # In short, software should avoid ruleless settings like TZ='EET-2EEST' 52 # and so should not depend on the value of POSIXRULES. 53 # 54 # If, despite the above, you want a template for handling these settings, 55 # you can change the line below (after finding the timezone you want in the 56 # one of the $(TDATA) source files, or adding it to a source file). 57 # Alternatively, if you discover you've got the wrong timezone, you can just 58 # 'zic -p -' to remove it, or 'zic -p rightzone' to change it. 59 # Use the command 60 # make zonenames 61 # to get a list of the values you can use for POSIXRULES. 62 63 POSIXRULES= - 64 65 # Also see TZDEFRULESTRING below, which takes effect only 66 # if the time zone files cannot be accessed. 67 68 69 # Installation locations. 70 # 71 # The defaults are suitable for Debian, except that if REDO is 72 # posix_right or right_posix then files that Debian puts under 73 # /usr/share/zoneinfo/posix and /usr/share/zoneinfo/right are instead 74 # put under /usr/share/zoneinfo-posix and /usr/share/zoneinfo-leaps, 75 # respectively.

Otherwise, the functions 342 # "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the 343 # time library, and if STD_INSPIRED is also defined the functions 344 # "posix2time_z" and "time2posix_z" are added as well. 345 # The functions ending in "_z" (or "_rz") are like their unsuffixed 346 # (or suffixed-by-"_r") counterparts, except with an extra first 347 # argument of opaque type timezone_t that specifies the timezone. 348 # "tzalloc" allocates a timezone_t value, and "tzfree" frees it. 349 # 350 # If you want to allocate state structures in localtime, add 351 # -DALL_STATE 352 # to the end of the "CFLAGS=" line.
