1 # Make and install tzdb code and data.
3 # This file is in the public domain, so clarified as of
4 # 2009-05-17 by Arthur David Olson.
6 # Package name for the code distribution.
9 # Version number for the distribution, overridden in the 'tarballs' rule below.
12 # Email address for bug reports.
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:
20 # To wait a while before using new features, to give downstream users
21 # time to upgrade zic (the default), use:
23 # To wait even longer for new features, use:
25 # Rearguard users might also want "ZFLAGS = -b fat"; see below.
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.
34 # to get a list of the values you can use for LOCALTIME.
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.
44 # If POSIXRULES is '-', no template is installed; this is the default.
46 # Any other value for POSIXRULES is obsolete and should not be relied on, as: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.
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.
61 # to get a list of the values you can use for POSIXRULES.
65 # Also see TZDEFRULESTRING below, which takes effect only
66 # if the time zone files cannot be accessed.
69 # Installation locations.
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. Problems with the Debian approach are discussed in
76 # the commentary for the right_posix rule (below).
78 # Destination directory, which can be used for staging.
79 # 'make DESTDIR=/stage install' installs under /stage (e.g., to
80 # /stage/etc/localtime instead of to /etc/localtime). Files under
81 # /stage are not intended to work as-is, but can be copied by hand to
82 # the root directory later. If DESTDIR is empty, 'make install' does
83 # not stage, but installs directly into production locations.
86 # Everything is installed into subdirectories of TOPDIR, and used there.
87 # TOPDIR should be empty (meaning the root directory),
88 # or a directory name that does not end in "/".
89 # TOPDIR should be empty or an absolute name unless you're just testing.

130 # If you want only POSIX time, with time values interpreted as
131 # seconds since the epoch (not counting leap seconds), use
133 # below. If you want only "right" time, with values interpreted
134 # as seconds since the epoch (counting leap seconds), use
136 # below. If you want both sets of data available, with leap seconds not
137 # counted normally, use
139 # below. If you want both sets of data available, with leap seconds counted
142 # below. POSIX mandates that leap seconds not be counted; for compatibility
143 # with it, use "posix_only" or "posix_right". Use POSIX time on systems with
144 # leap smearing; this can work better than unsmeared "right" time with
145 # applications that are not leap second aware, and is closer to unsmeared
146 # "right" time than unsmeared POSIX time is (e.g., 0.5 vs 1.0 s max error).
150 # Whether to put an "Expires" line in the leapseconds file.
151 # Use EXPIRES_LINE=1 to put the line in, 0 to omit it.
152 # The EXPIRES_LINE value matters only if REDO's value contains "right".
153 # If you change EXPIRES_LINE, remove the leapseconds file before running "make".
154 # zic's support for the Expires line was introduced in tzdb 2020a,

291 # The next batch of options control support for external variables
292 # exported by tzcode. In practice these variables are less useful
293 # than TM_GMTOFF and TM_ZONE. However, most of them are standardized.

301 # # Warning: unless time_tz is also defined, HAVE_TZNAME=1 can cause
302 # # crashes when combined with some platforms' standard libraries,
303 # # presumably due to memory allocation issues.

325 # "offtime", "timelocal", "timegm", "timeoff",
326 # "posix2time", and "time2posix" to be added to the time conversion library.
327 # "offtime" is like "gmtime" except that it accepts a second (long) argument
328 # that gives an offset to add to the time_t when converting it.
329 # "timelocal" is equivalent to "mktime".
330 # "timegm" is like "timelocal" except that it turns a struct tm into
331 # a time_t using UT (rather than local time as "timelocal" does).
332 # "timeoff" is like "timegm" except that it accepts a second (long) argument
333 # that gives an offset to use when converting to a time_t.
334 # "posix2time" and "time2posix" are described in an included manual page.
335 # X3J11's work does not describe any of these functions.
336 # These functions may well disappear in future releases of the time
337 # conversion package.
339 # If you don't want functions that were inspired by NetBSD, add
340 # -DNETBSD_INSPIRED=0
341 # to the end of the "CFLAGS=" line. 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.
