This arrange for "timezone" and "daylight" 27# variables to be kept up-to-date by the time conversion functions. Neither 28# "timezone" nor "daylight" is described in X3J11's work. 29# 30# If your system has a "GMT offset" field in its "struct tm"s 31# (or if you decide to add such a field in your system's "time.h" file), 32# add the name to a define such as 33# -DTM_GMTOFF=tm_gmtoff 34# or 35# -DTM_GMTOFF=_tm_gmtoff 36# to the end of the "CFLAGS=" line. 37# Neither tm_gmtoff nor _tm_gmtoff is described in X3J11's work; 38# in its work, use of "tm_gmtoff" is described as non-conforming. 39# Both Linux and BSD have done the equivalent of defining TM_GMTOFF in 40# their recent releases. 41# 42# If your system has a "zone abbreviation" field in its "struct tm"s 43# (or if you decide to add such a field in your system's "time.h" file), 44# add the name to a define such as 45# -DTM_ZONE=tm_zone 46# or 47# -DTM_ZONE=_tm_zone 48# to the end of the "CFLAGS=" line. 49# Neither tm_zone nor _tm_zone is described in X3J11's work; 50# in its work, use of "tm_zone" is described as non-conforming. 51# Both UCB and Sun have done the equivalent of defining TM_ZONE in 52# their recent releases. 53# 54# If you want functions that were inspired by early versions of X3J11's work, 55# add 56# -DSTD_INSPIRED 57# to the end of the "CFLAGS=" line. This arranges for the functions 58# "tzsetwall", "offtime", "timelocal", "timegm", "timeoff", 59# "posix2time", and "time2posix" to be added to the time conversion library. 60# "tzsetwall" is like "tzset" except that it arranges for local wall clock 61# time (rather than the time specified in the TZ environment variable) 62# to be used. 63# "offtime" is like "gmtime" except that it accepts a second (long) argument 64# that gives an offset to add to the time_t when converting it. 65# "timelocal" is equivalent to "mktime". 66# "timegm" is like "timelocal" except that it turns a struct tm into 67# a time_t using UTC (rather than local time as "timelocal" does). 68# "timeoff" is like "timegm" except that it accepts a second (long) argument 69# that gives an offset to use when converting to a time_t. 70# "posix2time" and "time2posix" are described in an included manual page. 71# X3J11's work does not describe any of these functions. 72# Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0. 73# These functions may well disappear in future releases of the time 74# conversion package. 75# 76# If you want Source Code Control System ID's left out of object modules, add 77# -DNOID 78# to the end of the "CFLAGS=" line. 79# 80# NIST-PCTS:151-2, Version 1.4, (1993-12-03) is a test suite put 81# out by the National Institute of Standards and Technology 82# which claims to test C and Posix conformance.
