243 # to the end of the "CFLAGS=" line. If not defined, the code attempts to
244 # guess TM_GMTOFF from other macros; define NO_TM_GMTOFF to suppress this.
245 # Similarly, if your system has a "zone abbreviation" field, define
247 # and define NO_TM_ZONE to suppress any guessing. These two fields are not
248 # required by POSIX, but are widely available on GNU/Linux and BSD systems.
250 # The next batch of options control support for external variables
251 # exported by tzcode. In practice these variables are less useful
252 # than TM_GMTOFF and TM_ZONE. However, most of them are standardized.
254 # # To omit or support the external variable "tzname", add one of:
257 # # to the "CFLAGS=" line. "tzname" is required by POSIX 1988 and later.
258 # # If not defined, the code attempts to guess HAVE_TZNAME from other macros.
259 # # Warning: unless time_tz is also defined, HAVE_TZNAME=1 can cause
260 # # crashes when combined with some platforms' standard libraries,
261 # # presumably due to memory allocation issues.
263 # # To omit or support the external variables "timezone" and "daylight", add
266 # # to the "CFLAGS=" line; "timezone" and "daylight" are inspired by
267 # # Unix Systems Group code and are required by POSIX 2008 (with XSI) and later.
268 # # If not defined, the code attempts to guess USG_COMPAT from other macros.
270 # # To support the external variable "altzone", add
272 # # to the end of the "CFLAGS=" line; although "altzone" appeared in
273 # # System V Release 3.1 it has not been standardized.

278 # to the end of the "CFLAGS=" line. This arranges for the functions
279 # "tzsetwall", "offtime", "timelocal", "timegm", "timeoff",
280 # "posix2time", and "time2posix" to be added to the time conversion library.
281 # "tzsetwall" is like "tzset" except that it arranges for local wall clock
282 # time (rather than the time specified in the TZ environment variable)
284 # "offtime" is like "gmtime" except that it accepts a second (long) argument
285 # that gives an offset to add to the time_t when converting it.
286 # "timelocal" is equivalent to "mktime".
287 # "timegm" is like "timelocal" except that it turns a struct tm into
288 # a time_t using UT (rather than local time as "timelocal" does).
289 # "timeoff" is like "timegm" except that it accepts a second (long) argument
290 # that gives an offset to use when converting to a time_t.
291 # "posix2time" and "time2posix" are described in an included manual page.
292 # X3J11's work does not describe any of these functions.
293 # Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0.
294 # These functions may well disappear in future releases of the time
295 # conversion package.
297 # If you don't want functions that were inspired by NetBSD, add
298 # -DNETBSD_INSPIRED=0
299 # to the end of the "CFLAGS=" line. Otherwise, the functions
300 # "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the
301 # time library, and if STD_INSPIRED is also defined the functions
302 # "posix2time_z" and "time2posix_z" are added as well.
303 # The functions ending in "_z" (or "_rz") are like their unsuffixed
304 # (or suffixed-by-"_r") counterparts, except with an extra first
305 # argument of opaque type timezone_t that specifies the time zone.
306 # "tzalloc" allocates a timezone_t value, and "tzfree" frees it.

320 # to the end of the "CFLAGS=" line. This causes "strftime" to always return
