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:
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
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 # 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
53 # to get a list of the values you can use for POSIXRULES.
55 # If POSIXRULES is empty, no template is installed; this is the intended
56 # future default for POSIXRULES.
58 # Nonempty POSIXRULES is obsolete and should not be relied on, because: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.

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. Problems with the Debian approach are discussed in
79 # the commentary for the right_posix rule (below).
81 # Destination directory, which can be used for staging.
82 # 'make DESTDIR=/stage install' installs under /stage (e.g., to
83 # /stage/etc/localtime instead of to /etc/localtime). Files under
84 # /stage are not intended to work as-is, but can be copied by hand to
85 # the root directory later. If DESTDIR is empty, 'make install' does
86 # not stage, but installs directly into production locations.

133 # If you want only POSIX time, with time values interpreted as
134 # seconds since the epoch (not counting leap seconds), use

137 # as seconds since the epoch (counting leap seconds), use
139 # below. If you want both sets of data available, with leap seconds not
140 # counted normally, use
142 # below. If you want both sets of data available, with leap seconds counted
145 # below. POSIX mandates that leap seconds not be counted; for compatibility
146 # with it, use "posix_only" or "posix_right". Use POSIX time on systems with
147 # leap smearing; this can work better than unsmeared "right" time with
148 # applications that are not leap second aware, and is closer to unsmeared
149 # "right" time than unsmeared POSIX time is (e.g., 0.5 vs 1.0 s max error).

154 # Use EXPIRES_LINE=1 to put the line in, 0 to omit it.

156 # If you change EXPIRES_LINE, remove the leapseconds file before running "make".
157 # zic's support for the Expires line was introduced in tzdb 2020a,

342 # "timegm" is like "timelocal" except that it turns a struct tm into
343 # a time_t using UT (rather than local time as "timelocal" does).
344 # "timeoff" is like "timegm" except that it accepts a second (long) argument
345 # that gives an offset to use when converting to a time_t.
346 # "posix2time" and "time2posix" are described in an included manual page.
347 # X3J11's work does not describe any of these functions.
348 # These functions may well disappear in future releases of the time
349 # conversion package.
351 # If you don't want functions that were inspired by NetBSD, add
352 # -DNETBSD_INSPIRED=0
353 # to the end of the "CFLAGS=" line. Otherwise, the functions
354 # "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the
355 # time library, and if STD_INSPIRED is also defined the functions
356 # "posix2time_z" and "time2posix_z" are added as well.
357 # The functions ending in "_z" (or "_rz") are like their unsuffixed
358 # (or suffixed-by-"_r") counterparts, except with an extra first
359 # argument of opaque type timezone_t that specifies the timezone.
360 # "tzalloc" allocates a timezone_t value, and "tzfree" frees it.
