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

88 # below. POSIX mandates that leap seconds not be counted; for compatibility
89 # with it, use "posix_only" or "posix_right". Use POSIX time on systems with
90 # leap smearing; this can work better than unsmeared "right" time with
91 # applications that are not leap second aware, and is closer to unsmeared

213 # to the end of the "CFLAGS=" line. If not defined, the code attempts to
214 # guess TM_GMTOFF from other macros; define NO_TM_GMTOFF to suppress this.
215 # Similarly, if your system has a "zone abbreviation" field, define
217 # and define NO_TM_ZONE to suppress any guessing. These two fields are not
218 # required by POSIX, but are widely available on GNU/Linux and BSD systems.
220 # The next batch of options control support for external variables
221 # exported by tzcode. In practice these variables are less useful
222 # than TM_GMTOFF and TM_ZONE. However, most of them are standardized.
224 # # To omit or support the external variable "tzname", add one of:
227 # # to the "CFLAGS=" line. "tzname" is required by POSIX 1988 and later.
228 # # If not defined, the code attempts to guess HAVE_TZNAME from other macros.
229 # # Warning: unless time_tz is also defined, HAVE_TZNAME=1 can cause
230 # # crashes when combined with some platforms' standard libraries,
231 # # presumably due to memory allocation issues.
233 # # To omit or support the external variables "timezone" and "daylight", add
236 # # to the "CFLAGS=" line; "timezone" and "daylight" are inspired by
237 # # Unix Systems Group code and are required by POSIX 2008 (with XSI) and later.
238 # # If not defined, the code attempts to guess USG_COMPAT from other macros.
240 # # To support the external variable "altzone", add
242 # # to the end of the "CFLAGS=" line; although "altzone" appeared in
243 # # System V Release 3.1 it has not been standardized.
245 # If you want functions that were inspired by early versions of X3J11's work,
248 # to the end of the "CFLAGS=" line. This arranges for the functions
249 # "tzsetwall", "offtime", "timelocal", "timegm", "timeoff",
250 # "posix2time", and "time2posix" to be added to the time conversion library.
251 # "tzsetwall" is like "tzset" except that it arranges for local wall clock
252 # time (rather than the time specified in the TZ environment variable)
254 # "offtime" is like "gmtime" except that it accepts a second (long) argument
255 # that gives an offset to add to the time_t when converting it.
256 # "timelocal" is equivalent to "mktime".
257 # "timegm" is like "timelocal" except that it turns a struct tm into
258 # a time_t using UT (rather than local time as "timelocal" does).
259 # "timeoff" is like "timegm" except that it accepts a second (long) argument
260 # that gives an offset to use when converting to a time_t.
261 # "posix2time" and "time2posix" are described in an included manual page.
262 # X3J11's work does not describe any of these functions.
263 # Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0.
264 # These functions may well disappear in future releases of the time
265 # conversion package.
267 # If you don't want functions that were inspired by NetBSD, add
268 # -DNETBSD_INSPIRED=0
269 # to the end of the "CFLAGS=" line. Otherwise, the functions
270 # "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the
271 # time library, and if STD_INSPIRED is also defined the functions
272 # "posix2time_z" and "time2posix_z" are added as well.
273 # The functions ending in "_z" (or "_rz") are like their unsuffixed
274 # (or suffixed-by-"_r") counterparts, except with an extra first
275 # argument of opaque type timezone_t that specifies the time zone.
276 # "tzalloc" allocates a timezone_t value, and "tzfree" frees it.
278 # If you want to allocate state structures in localtime, add
280 # to the end of the "CFLAGS=" line. Storage is obtained by calling malloc.

283 # out by the National Institute of Standards and Technology
284 # which claims to test C and Posix conformance. If you want to pass PCTS, add
286 # to the end of the "CFLAGS=" line.
288 # If you want strict compliance with XPG4 as of 1994-04-09, add
290 # to the end of the "CFLAGS=" line. This causes "strftime" to always return
