32744Swollman# Old rules, should the need arise.
42744Swollman# No attempt is made to handle Newfoundland, since it cannot be expressed
52744Swollman# using the System V "TZ" scheme (half-hour offset), or anything outside
62744Swollman# North America (no support for non-standard DST start/end dates), nor
775264Swollman# the change in the DST rules in the US in 1987 (which occurred before
875264Swollman# the old rules were written).

1075264Swollman# If you need the old rules, uncomment ## lines and comment-out Link lines.
1175264Swollman# Compile this *without* leap second correction for true conformance.
