23# Explanations of flags:
24#
25# If you want to use System V compatibility code, add
26#	-DUSG_COMPAT
27# to the end of the "CFLAGS=" line.  This arrange for "timezone" and "daylight"
28# variables to be kept up-to-date by the time conversion functions.  Neither
29# "timezone" nor "daylight" is described in X3J11's work.
30#
31# If your system has a "GMT offset" field in its "struct tm"s
32# (or if you decide to add such a field in your system's "time.h" file),
33# add the name to a define such as
34#	-DTM_GMTOFF=tm_gmtoff
35# or
36#	-DTM_GMTOFF=_tm_gmtoff
37# to the end of the "CFLAGS=" line.
38# Neither tm_gmtoff nor _tm_gmtoff is described in X3J11's work;
39# in its work, use of "tm_gmtoff" is described as non-conforming.
40# Both Linux and BSD have done the equivalent of defining TM_GMTOFF in
41# their recent releases.
42#
43# If your system has a "zone abbreviation" field in its "struct tm"s
44# (or if you decide to add such a field in your system's "time.h" file),
45# add the name to a define such as
46#	-DTM_ZONE=tm_zone
47# or
48#	-DTM_ZONE=_tm_zone
49# to the end of the "CFLAGS=" line.
50# Neither tm_zone nor _tm_zone is described in X3J11's work;
51# in its work, use of "tm_zone" is described as non-conforming.
52# Both UCB and Sun have done the equivalent of defining TM_ZONE in
53# their recent releases.
54#
55# If you want functions that were inspired by early versions of X3J11's work,
56# add
57#	-DSTD_INSPIRED
58# to the end of the "CFLAGS=" line.  This arranges for the functions
59# "tzsetwall", "offtime", "timelocal", "timegm", "timeoff",
60# "posix2time", and "time2posix" to be added to the time conversion library.
61# "tzsetwall" is like "tzset" except that it arranges for local wall clock
62# time (rather than the time specified in the TZ environment variable)
63# to be used.
64# "offtime" is like "gmtime" except that it accepts a second (long) argument
65# that gives an offset to add to the time_t when converting it.
66# "timelocal" is equivalent to "mktime".
67# "timegm" is like "timelocal" except that it turns a struct tm into
68# a time_t using UTC (rather than local time as "timelocal" does).
69# "timeoff" is like "timegm" except that it accepts a second (long) argument
70# that gives an offset to use when converting to a time_t.
71# "posix2time" and "time2posix" are described in an included manual page.
72# X3J11's work does not describe any of these functions.
73# Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0.
74# These functions may well disappear in future releases of the time
75# conversion package.
76#
77# If you want Source Code Control System ID's left out of object modules, add
78#	-DNOID
79# to the end of the "CFLAGS=" line.
80#
81# NIST-PCTS:151-2, Version 1.4, (1993-12-03) is a test suite put
82# out by the National Institute of Standards and Technology
83# which claims to test C and Posix conformance.  If you want to pass PCTS, add
84#	-DPCTS
85# to the end of the "CFLAGS=" line.
