This arranges for the functions 170# "tzsetwall", "offtime", "timelocal", "timegm", "timeoff", 171# "posix2time", and "time2posix" to be added to the time conversion library. 172# "tzsetwall" is like "tzset" except that it arranges for local wall clock 173# time (rather than the time specified in the TZ environment variable) 174# to be used. 175# "offtime" is like "gmtime" except that it accepts a second (long) argument 176# that gives an offset to add to the time_t when converting it. 177# "timelocal" is equivalent to "mktime". 178# "timegm" is like "timelocal" except that it turns a struct tm into 179# a time_t using UTC (rather than local time as "timelocal" does). 180# "timeoff" is like "timegm" except that it accepts a second (long) argument 181# that gives an offset to use when converting to a time_t. 182# "posix2time" and "time2posix" are described in an included manual page. 183# X3J11's work does not describe any of these functions. 184# Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0. 185# These functions may well disappear in future releases of the time 186# conversion package. 187# 188# If you want Source Code Control System ID's left out of object modules, add 189# -DNOID 190# to the end of the "CFLAGS=" line. 191# 192# If you'll never want to handle solar-time-based time zones, add 193# -DNOSOLAR 194# to the end of the "CFLAGS=" line 195# (and comment out the "SDATA=" line below). 196# This reduces (slightly) the run-time data-space requirements of 197# the time conversion functions; it may reduce the acceptability of your system 198# to folks in oil- and cash-rich places. 199# 200# If you want to allocate state structures in localtime, add 201# -DALL_STATE 202# to the end of the "CFLAGS=" line.
