# 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 UT offsets of standard and
# summer time.)
# Alternately, if you discover you've got the wrong time zone, you can just
#	zic -p rightzone
# to correct things.
# Use the command
#	make zonenames
# to get a list of the values you can use for POSIXRULES.
# If you want POSIX compatibility, use "America/New_York".

# "Compiled" time zone information is placed in the "TZDIR" directory

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

#	REDO=		right_only
# below.  If you want both sets of data available, with leap seconds not
# counted normally, use
