# Alternately, if you discover you've got the wrong time zone, you can just

# If you want something other than Eastern United States time as a template
# for handling POSIX-style time zone environment variables,
# change the line below (after finding the zone you want in the
# time zone files, or adding it to a time zone file).
# (When a POSIX-style environment variable is handled, the rules in the
# template file are used to determine "spring forward" and "fall back" days and
# times; the environment variable itself specifies UTC offsets of standard and
# summer time.)
# Alternately, if you discover you've got the wrong time zone, you can just
# zic -p rightzone

# -DHAVE_GETTEXT=1 if `gettext' works (GNU, Linux, Solaris); also see LDLIBS
# -DHAVE_INCOMPATIBLE_CTIME_R=1 if your system's time.h declares

# -DHAVE_SETTIMEOFDAY=0 if settimeofday does not exist (SVR0?)

# -DHAVE_SETTIMEOFDAY=3 if settimeofday ignores 2nd arg (4.4BSD)
# -DHAVE_STDINT_H=1 if you have a pre-C99 compiler with "stdint.h"
# -DHAVE_SYMLINK=0 if your system lacks the symlink function
# -DHAVE_SYS_STAT_H=0 if your compiler lacks a "sys/stat.h"
# -DHAVE_SYS_WAIT_H=0 if your compiler lacks a "sys/wait.h"
# -DLOCALE_HOME=\"path\" if locales are in "path", not "/usr/lib/locale"
# -DHAVE_UNISTD_H=0 if your compiler lacks a "unistd.h" (Microsoft C++ 7?)
# -DHAVE_UTMPX_H=1 if your compiler has a "utmpx.h"
# -DTZDEFRULESTRING=\",date/time,date/time\" to default to the specified
# DST transitions if the time zone files cannot be accessed
# -DTZ_DOMAIN=\"foo\" to use "foo" for gettext domain name; default is "tz"
# -TTZ_DOMAINDIR=\"/path\" to use "/path" for gettext directory;
# the default is system-supplied, typically "/usr/lib/locale"
# $(GCC_DEBUG_FLAGS) if you are using GCC and want lots of checking
# -DNO_RUN_TIME_WARNINGS_ABOUT_YEAR_2000_PROBLEMS_THANK_YOU=1

#
# If you want to use System V compatibility code, add
# -DUSG_COMPAT
# to the end of the "CFLAGS=" line. This arrange for "timezone" and "daylight"
# variables to be kept up-to-date by the time conversion functions. Neither
# "timezone" nor "daylight" is described in X3J11's work.
#
# If your system has a "GMT offset" field in its "struct tm"s
# (or if you decide to add such a field in your system's "time.h" file),
# add the name to a define such as
# -DTM_GMTOFF=tm_gmtoff
# or
# -DTM_GMTOFF=_tm_gmtoff
# to the end of the "CFLAGS=" line.
# Neither tm_gmtoff nor _tm_gmtoff is described in X3J11's work;
# in its work, use of "tm_gmtoff" is described as non-conforming.
# Both Linux and BSD have done the equivalent of defining TM_GMTOFF in
# their recent releases.
#
# 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 the name to a define such as
# -DTM_ZONE=tm_zone
# or
# -DTM_ZONE=_tm_zone
# to the end of the "CFLAGS=" line.
# Neither tm_zone nor _tm_zone is described in X3J11's work;
# in its work, use of "tm_zone" is described as non-conforming.
# Both UCB and Sun have done the equivalent of defining TM_ZONE in
# their recent releases.
#
# If you want functions that were inspired by early versions of X3J11's work,
# add
# -DSTD_INSPIRED
# to the end of the "CFLAGS=" line. This arranges for the functions
# "tzsetwall", "offtime", "timelocal", "timegm", "timeoff",
# "posix2time", and "time2posix" 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 UTC (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.
# "posix2time" and "time2posix" are described in an included manual page.
# X3J11's work does not describe any of these functions.
# Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0.
# These functions may well disappear in future releases of the time
# conversion package.
#
# 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.
#
# NIST-PCTS:151-2, Version 1.4, (1993-12-03) is a test suite put
# out by the National Institute of Standards and Technology
# which claims to test C and Posix conformance. If you want to pass PCTS, add
# -DPCTS
# to the end of the "CFLAGS=" line.
#
# If you want strict compliance with XPG4 as of 1994-04-09, add
# -DXPG4_1994_04_09
# to the end of the "CFLAGS=" line. This causes "strftime" to always return
# 53 as a week number (rather than 52 or 53) for those days in January that
# before the first Monday in January when a "%V" format is used and January 1
# falls on a Friday, Saturday, or Sunday.
