|

# If you want to use System V compatibility code, add

|
# If your system has a "GMT offset" field in its "struct tm"s

# -DTM_GMTOFF=_tm_gmtoff
|

# Neither tm_gmtoff nor _tm_gmtoff is described in X3J11's work;

# in its work, use of "tm_gmtoff" is described as non-conforming.

|
# If your system has a "zone abbreviation" field in its "struct tm"s
|
|
# (or if you decide to add such a field in your system's "time.h" file),

|
# add
|
|
# -DSTD_INSPIRED
|
|
# to the end of the "CFLAGS=" line. This arranges for the functions
|
|
# "tzsetwall", "offtime", "timelocal", "timegm", and "timeoff"
|
|
# to be added to the time conversion library.
|
|
# "tzsetwall" is like "tzset" except that it arranges for local wall clock
|
|
# time (rather than the time specified in the TZ environment variable)
|
|
# to be used.
|
|
# "offtime" is like "gmtime" except that it accepts a second (long) argument
|
|
# that gives an offset to add to the time_t when converting it.
|
|
# "timelocal" is equivalent to "mktime".
|
|
# "timegm" is like "timelocal" except that it turns a struct tm into
|
|
# a time_t using GMT (rather than local time as "timelocal" does).
|
|
# "timeoff" is like "timegm" except that it accepts a second (long) argument
|
|
# that gives an offset to use when converting to a time_t.
|
|
# None of these functions are described in X3J11's current work.
|
|
# Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0.
|
|
# These functions may well disappear in future releases of the time
|
|
# conversion package.

#
|
|
# XXX--NEED WORDS ON CONDITIONAL COMPILATION OF POSIX2TIME AND TIME2POSIX HERE!

# If you want Source Code Control System ID's left out of object modules, add
|
|
# -DNOID
|
|
# to the end of the "CFLAGS=" line.
|
|
#
|
|
# If you'll never want to handle solar-time-based time zones, add
|
|
# -DNOSOLAR
|
|
# to the end of the "CFLAGS=" line
|
|
# (and comment out the "SDATA=" line below).
|
|
# This reduces (slightly) the run-time data-space requirements of
|
|
# the time conversion functions; it may reduce the acceptability of your system
|
|
# to folks in oil- and cash-rich places.
|
|
#
|
|
# If you want to allocate state structures in localtime, add
|
|
# -DALL_STATE
|
|
# to the end of the "CFLAGS=" line. Storage is obtained by calling malloc.
|
|
#
|
|
# If you want an "altzone" variable (a la System V Release 3.1), add
|
|
# -DALTZONE
|
|
# to the end of the "CFLAGS=" line.
|
|
# This variable is not described in X3J11's work.
|
|
#
|
|
# If you want a "gtime" function (a la MACH), add
|
|
# -DCMUCS
|
|
# to the end of the "CFLAGS=" line
|
|
# This function is not described in X3J11's work.
