26 # Alternatively, if you discover you've got the wrong timezone, you can just
31 # to get a list of the values you can use for LOCALTIME.
35 # If you want something other than Eastern United States time as a template
36 # for handling POSIX-style timezone environment variables,
37 # change the line below (after finding the timezone you want in the
38 # one of the $(TDATA) source files, or adding it to a source file).
39 # When a POSIX-style environment variable is handled, the rules in the
40 # template file are used to determine "spring forward" and "fall back" days and
41 # times; the environment variable itself specifies UT offsets of standard and
42 # daylight saving time.
43 # Alternatively, if you discover you've got the wrong timezone, you can just
48 # to get a list of the values you can use for POSIXRULES.

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

116 # What kind of TZif data files to generate.
117 # (TZif is the binary time zone data format that zic generates.)
118 # If you want only POSIX time, with time values interpreted as
119 # seconds since the epoch (not counting leap seconds), use
121 # below. If you want only "right" time, with values interpreted
122 # as seconds since the epoch (counting leap seconds), use
124 # below. If you want both sets of data available, with leap seconds not
125 # counted normally, use
127 # below. If you want both sets of data available, with leap seconds counted
130 # below. POSIX mandates that leap seconds not be counted; for compatibility
131 # with it, use "posix_only" or "posix_right". Use POSIX time on systems with
132 # leap smearing; this can work better than unsmeared "right" time with
133 # applications that are not leap second aware, and is closer to unsmeared
134 # "right" time than unsmeared POSIX time is (e.g., 0.5 vs 1.0 s max error).
138 # To install data in text form that has all the information of the TZif data,
139 # (optionally incorporating leap second information), use
140 # TZDATA_TEXT= tzdata.zi leapseconds
141 # To install text data without leap second information (e.g., because

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

280 # # Warning: unless time_tz is also defined, HAVE_TZNAME=1 can cause
281 # # crashes when combined with some platforms' standard libraries,
282 # # presumably due to memory allocation issues.
284 # # To omit or support the external variables "timezone" and "daylight", add
287 # # to the "CFLAGS=" line; "timezone" and "daylight" are inspired by
288 # # Unix Systems Group code and are required by POSIX 2008 (with XSI) and later.

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

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

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