# 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
# to correct things.

# In earlier versions of this makefile, the other two directories were
# subdirectories of $(TZDIR).  However, this led to configuration errors.
# For example, with posix_right under the earlier scheme,
# TZ='right/Australia/Adelaide' got you localtime with leap seconds,
# but gmtime without leap seconds, which led to problems with applications
# like sendmail that subtract gmtime from localtime.
# Therefore, the other two directories are now siblings of $(TZDIR).
# You must replace all of $(TZDIR) to switch from not using leap seconds
# to using them, or vice versa.
