5023N/A# Old rules, should the need arise.

5023N/A# No attempt is made to handle Newfoundland, since it cannot be expressed

5023N/A# using the System V "TZ" scheme (half-hour offset), or anything outside

5023N/A# North America (no support for non-standard DST start/end dates), nor

5023N/A# the changes in the DST rules in the US after 1976 (which occurred after

5023N/A# the old rules were written).

5023N/A#

5023N/A# If you need the old rules, uncomment ## lines.

5023N/A# Compile this *without* leap second correction for true conformance.
