# tzdb data for System V rules (this file is obsolete)
|
|
|
|
# This file is in the public domain, so clarified as of
|
|
# 2009-05-17 by Arthur David Olson.
|
|
|
|
# Old rules, should the need arise.
|
|
# No attempt is made to handle Newfoundland, since it cannot be expressed
|
|
# using the System V "TZ" scheme (half-hour offset), or anything outside
|
|
# North America (no support for non-standard DST start/end dates), nor
|
|
# the changes in the DST rules in the US after 1976 (which occurred after
|
|
# the old rules were written).
|
|
#
|
|
# If you need the old rules, uncomment ## lines.
|
|
# Compile this *without* leap second correction for true conformance.
