This arrange for "timezone" and "daylight" 163# variables to be kept up-to-date by the time conversion functions. Neither 164# "timezone" nor "daylight" is described in X3J11's work. 165# 166# If your system has a "GMT offset" field in its "struct tm"s 167# (or if you decide to add such a field in your system's "time.h" file), 168# add the name to a define such as 169# -DTM_GMTOFF=tm_gmtoff 170# to the end of the "CFLAGS=" line. If not defined, the code attempts to 171# guess TM_GMTOFF from other macros; define NO_TM_GMTOFF to suppress this. 172# Similarly, if your system has a "zone abbreviation" field, define 173# -DTM_ZONE=tm_zone 174# and define NO_TM_ZONE to suppress any guessing. These two fields are not 175# required by POSIX, but are widely available on GNU/Linux and BSD systems. 176# 177# If you want functions that were inspired by early versions of X3J11's work, 178# add 179# -DSTD_INSPIRED 180# to the end of the "CFLAGS=" line. This arranges for the functions 181# "tzsetwall", "offtime", "timelocal", "timegm", "timeoff", 182# "posix2time", and "time2posix" to be added to the time conversion library. 183# "tzsetwall" is like "tzset" except that it arranges for local wall clock 184# time (rather than the time specified in the TZ environment variable) 185# to be used. 186# "offtime" is like "gmtime" except that it accepts a second (long) argument 187# that gives an offset to add to the time_t when converting it. 188# "timelocal" is equivalent to "mktime". 189# "timegm" is like "timelocal" except that it turns a struct tm into 190# a time_t using UT (rather than local time as "timelocal" does). 191# "timeoff" is like "timegm" except that it accepts a second (long) argument 192# that gives an offset to use when converting to a time_t. 193# "posix2time" and "time2posix" are described in an included manual page. 194# X3J11's work does not describe any of these functions. 195# Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0. 196# These functions may well disappear in future releases of the time 197# conversion package. 198# 199# If you don't want functions that were inspired by NetBSD, add 200# -DNETBSD_INSPIRED=0 201# to the end of the "CFLAGS=" line. Otherwise, the functions 202# "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the 203# time library, and if STD_INSPIRED is also defined the functions 204# "posix2time_z" and "time2posix_z" are added as well. 205# The functions ending in "_z" (or "_rz") are like their unsuffixed 206# (or suffixed-by-"_r") counterparts, except with an extra first 207# argument of opaque type timezone_t that specifies the time zone. 208# "tzalloc" allocates a timezone_t value, and "tzfree" frees it. 209# 210# If you want to allocate state structures in localtime, add 211# -DALL_STATE 212# to the end of the "CFLAGS=" line. Storage is obtained by calling malloc. 213# 214# If you want an "altzone" variable (a la System V Release 3.1), add 215# -DALTZONE 216# to the end of the "CFLAGS=" line. 217# This variable is not described in X3J11's work. 218# 219# NIST-PCTS:151-2, Version 1.4, (1993-12-03) is a test suite put 220# out by the National Institute of Standards and Technology 221# which claims to test C and Posix conformance. If you want to pass PCTS, add 222# -DPCTS 223# to the end of the "CFLAGS=" line. 224# 225# If you want strict compliance with XPG4 as of 1994-04-09, add 226# -DXPG4_1994_04_09 227# to the end of the "CFLAGS=" line.
