+# 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.
