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
49#	zic -p rightzone
50# to correct things.
51# Use the command
52#	make zonenames
53# to get a list of the values you can use for POSIXRULES.
54#
55# If POSIXRULES is empty, no template is installed; this is the intended
56# future default for POSIXRULES.
57#
58# Nonempty POSIXRULES is obsolete and should not be relied on, because: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.

133# If you want only POSIX time, with time values interpreted as

143# normally, use
144#	REDO=		right_posix
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

217#	(Solaris when _POSIX_PTHREAD_SEMANTICS is not defined).
218#  -DHAVE_INTTYPES_H if you have a non-C99 compiler with <inttypes.h>

220#  -DHAVE_LOCALTIME_R=0 if your system lacks a localtime_r function
221#  -DHAVE_LOCALTIME_RZ=0 if you do not want zdump to use localtime_rz
222#	localtime_rz can make zdump significantly faster, but is nonstandard.
223#  -DHAVE_POSIX_DECLS=0 if your system's include files do not declare
224#	functions like 'link' or variables like 'tzname' required by POSIX

239#  -Dssize_t=long on hosts like MS-Windows that lack ssize_t
240#  -DSUPPRESS_TZDIR to not prepend TZDIR to file names; this has
241#	security implications and is not recommended for general use
242#  -DTHREAD_SAFE to make localtime.c thread-safe, as POSIX requires;
243#	not needed by the main-program tz code, which is single-threaded.
244#	Append other compiler flags as needed, e.g., -pthread on GNU/Linux.
245#  -Dtime_tz=\"T\" to use T as the time_t type, rather than the system time_t
246#	This is intended for internal use only; it mangles external names.
247#  -DTZ_DOMAIN=\"foo\" to use "foo" for gettext domain name; default is "tz"
248#  -DTZ_DOMAINDIR=\"/path\" to use "/path" for gettext directory;
249#	the default is system-supplied, typically "/usr/lib/locale"

251#	DST transitions if the time zone files cannot be accessed
252#  -DUNINIT_TRAP if reading uninitialized storage can cause problems
253#	other than simply getting garbage data
254#  -DUSE_LTZ=0 to build zdump with the system time zone library
255#	Also set TZDOBJS=zdump.o and CHECK_TIME_T_ALTERNATIVES= below.
256#  -DZIC_BLOAT_DEFAULT=\"slim\" to default zic's -b option to "slim", and

258#	and bugs in some TZif readers, notably readers that mishandle 64-bit
259#	data in TZif files.  Slim TZif files are more efficient and do not
260#	work around these incompatibilities and bugs.  If not given, the

262#	requiring fat files often mishandle timestamps after 2037 anyway.
263#  -DZIC_MAX_ABBR_LEN_WO_WARN=3

297# Similarly, if your system has a "zone abbreviation" field, define
298#	-DTM_ZONE=tm_zone
299# and define NO_TM_ZONE to suppress any guessing.  These two fields are not
300# required by POSIX, but are widely available on GNU/Linux and BSD systems.
301#
302# The next batch of options control support for external variables
303# exported by tzcode.  In practice these variables are less useful
304# than TM_GMTOFF and TM_ZONE.  However, most of them are standardized.
305# #
306# # To omit or support the external variable "tzname", add one of:
307# #	-DHAVE_TZNAME=0 # do not support "tzname"
308# #	-DHAVE_TZNAME=1 # support "tzname", which is defined by system library
309# #	-DHAVE_TZNAME=2 # support and define "tzname"
310# # to the "CFLAGS=" line.  "tzname" is required by POSIX 1988 and later.
311# # If not defined, the code attempts to guess HAVE_TZNAME from other macros.
312# # Warning: unless time_tz is also defined, HAVE_TZNAME=1 can cause
313# # crashes when combined with some platforms' standard libraries,
314# # presumably due to memory allocation issues.
315# #
316# # To omit or support the external variables "timezone" and "daylight", add
317# #	-DUSG_COMPAT=0 # do not support
318# #	-DUSG_COMPAT=1 # support, and variables are defined by system library
319# #	-DUSG_COMPAT=2 # support and define variables
320# # to the "CFLAGS=" line; "timezone" and "daylight" are inspired by
321# # Unix Systems Group code and are required by POSIX 2008 (with XSI) and later.
322# # If not defined, the code attempts to guess USG_COMPAT from other macros.

329# # System V Release 3.1 it has not been standardized.
330# # If not defined, the code attempts to guess ALTZONE from other macros.

332# If you want functions that were inspired by early versions of X3J11's work,
333# add
334#	-DSTD_INSPIRED
335# to the end of the "CFLAGS=" line.  This arranges for the functions
336# "tzsetwall", "offtime", "timelocal", "timegm", "timeoff",
337# "posix2time", and "time2posix" to be added to the time conversion library.
338# "tzsetwall" is deprecated and is intended to be removed soon; see NEWS.
339# "offtime" is like "gmtime" except that it accepts a second (long) argument
340# that gives an offset to add to the time_t when converting it.
341# "timelocal" is equivalent to "mktime".
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.
350#
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.
