# Taken from the tzcode95g.tar.gz Makefile:
#
# 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 GMT 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.
# If you want POSIX compatibility, use "America/New_York".
