12 # Email address for bug reports.

17 # possibly with minor discrepancies that users are not likely to notice.

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 # If you want something other than Eastern United States time as a template
39 # for handling ruleless POSIX-style timezone environment variables,
40 # change the line below (after finding the timezone you want in the
41 # one of the $(TDATA) source files, or adding it to a source file).
42 # A ruleless environment setting like TZ='CST6CDT' uses the rules in the
43 # template file to determine "spring forward" and "fall back" days and
44 # times; the environment variable itself specifies UT offsets of standard and
45 # daylight saving time.
46 # Alternatively, if you discover you've got the wrong timezone, you can just
51 # to get a list of the values you can use for POSIXRULES.

61 # The defaults are suitable for Debian, except that if REDO is
62 # posix_right or right_posix then files that Debian puts under
63 # /usr/share/zoneinfo/posix and /usr/share/zoneinfo/right are instead
64 # put under /usr/share/zoneinfo-posix and /usr/share/zoneinfo-leaps,
65 # respectively. Problems with the Debian approach are discussed in
66 # the commentary for the right_posix rule (below).
68 # Destination directory, which can be used for staging.
69 # 'make DESTDIR=/stage install' installs under /stage (e.g., to
70 # /stage/etc/localtime instead of to /etc/localtime). Files under
71 # /stage are not intended to work as-is, but can be copied by hand to
72 # the root directory later. If DESTDIR is empty, 'make install' does
73 # not stage, but installs directly into production locations.
76 # Everything is installed into subdirectories of TOPDIR, and used there.
77 # TOPDIR should be empty (meaning the root directory),
78 # or a directory name that does not end in "/".
79 # TOPDIR should be empty or an absolute name unless you're just testing.

120 # If you want only POSIX time, with time values interpreted as
121 # seconds since the epoch (not counting leap seconds), use
123 # below. If you want only "right" time, with values interpreted
124 # as seconds since the epoch (counting leap seconds), use
126 # below. If you want both sets of data available, with leap seconds not
127 # counted normally, use
129 # below. If you want both sets of data available, with leap seconds counted
132 # below. POSIX mandates that leap seconds not be counted; for compatibility
133 # with it, use "posix_only" or "posix_right". Use POSIX time on systems with
134 # leap smearing; this can work better than unsmeared "right" time with
135 # applications that are not leap second aware, and is closer to unsmeared
136 # "right" time than unsmeared POSIX time is (e.g., 0.5 vs 1.0 s max error).

270 # and define NO_TM_ZONE to suppress any guessing. These two fields are not
271 # required by POSIX, but are widely available on GNU/Linux and BSD systems.
273 # The next batch of options control support for external variables
274 # exported by tzcode. In practice these variables are less useful
275 # than TM_GMTOFF and TM_ZONE. However, most of them are standardized.

282 # # Warning: unless time_tz is also defined, HAVE_TZNAME=1 can cause
283 # # crashes when combined with some platforms' standard libraries,
284 # # presumably due to memory allocation issues.
286 # # To omit or support the external variables "timezone" and "daylight", add
289 # # to the "CFLAGS=" line; "timezone" and "daylight" are inspired by
290 # # Unix Systems Group code and are required by POSIX 2008 (with XSI) and later.
291 # # If not defined, the code attempts to guess USG_COMPAT from other macros.
293 # # To support the external variable "altzone", add

302 # "tzsetwall", "offtime", "timelocal", "timegm", "timeoff",

304 # "tzsetwall" is like "tzset" except that it arranges for local wall clock
305 # time (rather than the timezone specified in the TZ environment variable)
307 # "offtime" is like "gmtime" except that it accepts a second (long) argument
308 # that gives an offset to add to the time_t when converting it.
309 # "timelocal" is equivalent to "mktime".
310 # "timegm" is like "timelocal" except that it turns a struct tm into
311 # a time_t using UT (rather than local time as "timelocal" does).
312 # "timeoff" is like "timegm" except that it accepts a second (long) argument
313 # that gives an offset to use when converting to a time_t.
314 # "posix2time" and "time2posix" are described in an included manual page.
315 # X3J11's work does not describe any of these functions.
316 # Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0.

318 # conversion package.

322 # to the end of the "CFLAGS=" line. Otherwise, the functions
323 # "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the
324 # time library, and if STD_INSPIRED is also defined the functions
325 # "posix2time_z" and "time2posix_z" are added as well.
326 # The functions ending in "_z" (or "_rz") are like their unsuffixed
327 # (or suffixed-by-"_r") counterparts, except with an extra first
328 # argument of opaque type timezone_t that specifies the timezone.
329 # "tzalloc" allocates a timezone_t value, and "tzfree" frees it.
