 # Pakistan

+# From Rives McDow (2002-03-13):
+# I have been advised that Pakistan has decided to adopt dst on a
+# TRIAL basis for one year, starting 00:01 local time on April 7, 2002
+# and ending at 00:01 local time October 6, 2002.  This is what I was
+# told, but I believe that the actual time of change may be 00:00; the
+# 00:01 was to make it clear which day it was on.
+
+# From Paul Eggert (2002-03-15):
+# Jesper Norgaard found this URL:
+# http://www.pak.gov.pk/public/news/app/app06_dec.htm
+# (dated 2001-12-06) which says that the Cabinet adopted a scheme "to
+# advance the clocks by one hour on the night between the first
+# Saturday and Sunday of April and revert to the original position on
+# 15th October each year".  This agrees with McDow's 04-07 at 00:00,
+# but disagrees about the October transition, and makes it sound like
+# it's not on a trial basis.  Also, the "between the first Saturday
+# and Sunday of April" phrase, if taken literally, means that the
+# transition takes place at 00:00 on the first Sunday on or after 04-02.
