+# establishing "Pacific Presidential Election Time"; it was not acted on
+# by the Senate or signed into law by the President.
+# You might want to change the "PE" (Presidential Election) below to
+# "Q" (Quadrennial) to maintain three-character zone abbreviations.
+# If you're really conservative, you might want to change it to "D".
+# Avoid "L" (Leap Year), which won't be true in 2100.

+# If Presidential Election Time is ever established, replace "XXXX" below
+# with the year the law takes effect and uncomment the "##" lines.
