37# When a POSIX-style environment variable is handled, the rules in the
38# template file are used to determine "spring forward" and "fall back" days and

57# The defaults are suitable for Debian, except that if REDO is
58# posix_right or right_posix then files that Debian puts under
59# /usr/share/zoneinfo/posix and /usr/share/zoneinfo/right are instead
60# put under /usr/share/zoneinfo-posix and /usr/share/zoneinfo-leaps,
61# respectively.  Problems with the Debian approach are discussed in
62# the commentary for the right_posix rule (below).
63
64# Destination directory, which can be used for staging.
65# 'make DESTDIR=/stage install' installs under /stage (e.g., to
66# /stage/etc/localtime instead of to /etc/localtime).  Files under
67# /stage are not intended to work as-is, but can be copied by hand to
68# the root directory later.  If DESTDIR is empty, 'make install' does
69# not stage, but installs directly into production locations.

125# with it, use "posix_only" or "posix_right".  Use POSIX time on systems with
126# leap smearing; this can work better than unsmeared "right" time with
127# applications that are not leap second aware, and is closer to unsmeared

216#  -Dtime_tz=\"T\" to use T as the time_t type, rather than the system time_t

255# If your system has a "GMT offset" field in its "struct tm"s

257# add the name to a define such as
258#	-DTM_GMTOFF=tm_gmtoff
259# to the end of the "CFLAGS=" line.  If not defined, the code attempts to
260# guess TM_GMTOFF from other macros; define NO_TM_GMTOFF to suppress this.
261# Similarly, if your system has a "zone abbreviation" field, define
262#	-DTM_ZONE=tm_zone
263# and define NO_TM_ZONE to suppress any guessing.  These two fields are not
264# required by POSIX, but are widely available on GNU/Linux and BSD systems.
265#
266# The next batch of options control support for external variables
267# exported by tzcode.  In practice these variables are less useful
268# than TM_GMTOFF and TM_ZONE.  However, most of them are standardized.
269# #
270# # To omit or support the external variable "tzname", add one of:
271# #	-DHAVE_TZNAME=0
272# #	-DHAVE_TZNAME=1
273# # to the "CFLAGS=" line.  "tzname" is required by POSIX 1988 and later.
274# # If not defined, the code attempts to guess HAVE_TZNAME from other macros.
275# # Warning: unless time_tz is also defined, HAVE_TZNAME=1 can cause
276# # crashes when combined with some platforms' standard libraries,
277# # presumably due to memory allocation issues.
278# #
279# # To omit or support the external variables "timezone" and "daylight", add
280# #	-DUSG_COMPAT=0
281# #	-DUSG_COMPAT=1
282# # to the "CFLAGS=" line; "timezone" and "daylight" are inspired by
283# # Unix Systems Group code and are required by POSIX 2008 (with XSI) and later.
284# # If not defined, the code attempts to guess USG_COMPAT from other macros.
285# #
286# # To support the external variable "altzone", add
287# #	-DALTZONE
288# # to the end of the "CFLAGS=" line; although "altzone" appeared in
289# # System V Release 3.1 it has not been standardized.
290#
291# If you want functions that were inspired by early versions of X3J11's work,
292# add
293#	-DSTD_INSPIRED
294# to the end of the "CFLAGS=" line.  This arranges for the functions
295# "tzsetwall", "offtime", "timelocal", "timegm", "timeoff",
296# "posix2time", and "time2posix" to be added to the time conversion library.
297# "tzsetwall" is like "tzset" except that it arranges for local wall clock
298# time (rather than the time specified in the TZ environment variable)
299# to be used.
300# "offtime" is like "gmtime" except that it accepts a second (long) argument
301# that gives an offset to add to the time_t when converting it.
302# "timelocal" is equivalent to "mktime".
303# "timegm" is like "timelocal" except that it turns a struct tm into
304# a time_t using UT (rather than local time as "timelocal" does).
305# "timeoff" is like "timegm" except that it accepts a second (long) argument
306# that gives an offset to use when converting to a time_t.
307# "posix2time" and "time2posix" are described in an included manual page.
308# X3J11's work does not describe any of these functions.
309# Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0.
310# These functions may well disappear in future releases of the time
311# conversion package.
312#
313# If you don't want functions that were inspired by NetBSD, add
314#	-DNETBSD_INSPIRED=0
315# to the end of the "CFLAGS=" line.  Otherwise, the functions
316# "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the
317# time library, and if STD_INSPIRED is also defined the functions
318# "posix2time_z" and "time2posix_z" are added as well.
319# The functions ending in "_z" (or "_rz") are like their unsuffixed
320# (or suffixed-by-"_r") counterparts, except with an extra first
321# argument of opaque type timezone_t that specifies the time zone.
322# "tzalloc" allocates a timezone_t value, and "tzfree" frees it.
323#
324# If you want to allocate state structures in localtime, add
325#	-DALL_STATE
326# to the end of the "CFLAGS=" line.  Storage is obtained by calling malloc.
