+# @(#)systemv  7.3
+
+# 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 change in the DST rules in the US in 1987 (which occurred before
+# the old rules were written).
+#
+# If you need the old rules, uncomment ## lines and comment-out Link lines.
+# Compile this *without* leap second correction for true conformance.
