# If you want something other than Eastern United States time used on your
# system, change the line below (after finding the zone you want in the
# time zone files, or adding it to a time zone file).
# Alternately, if you discover you've got the wrong time zone, you can just
#	zic -l rightzone

LOCALTIME=	US/Eastern

# Use an absolute path name for TZDIR unless you're just testing the software.

TZDIR=		/etc/zoneinfo

# You may want to change this define if you're just testing the software.
# Alternatively, you can put these functions in /lib/libc.a, removing
# the old "ctime.o" (and "timezone.o" on a BSD system).  This is the
# ideal solution if you are able.  Build libz.a, extract the files, and
# then add them to libc.a.

TZLIB=		/usr/lib/libz.a

#
# If you're running on a System V-style system and don't want lint grief,
# add
#	-DUSG
# to the end of the "CFLAGS=" line.
#
# If you're running on a system where "strchr" is known as "index",
# (for example, a 4.[012]BSD system), add
#	-Dstrchr=index
# to the end of the "CFLAGS=" line.
#
# If you want to use System V compatibility code, add
#	-DUSG_COMPAT
# to the end of the "CFLAGS=" line.
#
# If you want BSD compatibility code, add
#	-DBSD_COMPAT
# to the end of the "CFLAGS=" line.
#
# If you've used older versions of this software and want "tz_abbr"
# compatibility code, add
#	-DTZA_COMPAT
# to the end of the "CFLAGS=" line.
#
# If you'd like to use Robert Elz's additions to the "struct tm" structure,
# add a
#	-DKRE_COMPAT
# to the end of the "CFLAGS=" line, and add the structure elements
#	long	tm_gmtoff;
#	char *	tm_zone;
# to the END of the "struct tm" structure defined in "/usr/include/time.h".
#
# If you want code inspired by certain emerging standards, add
#	-DSTD_INSPIRED
# to the end of the "CFLAGS=" line.
#
# 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 remove solar87 and solar88 from the DATA= line below).
#

CFLAGS=

# LINTFLAGS is set for 4.[123]BSD systems.
# If you're using System V, you'll want to comment out the "LINTFLAGS=" line.
