+# Finally we've got the official mail regarding DST start time where DST start
+# time is mentioned as Jun 19 2009, 23:00 from BTRC (Bangladesh
+# Telecommunication Regulatory Commission).
+#
+# No DST end date has been announced yet.

+# From Arthur David Olson (2009-07-11):
+# Arbitrarily end DST at the end of 2009 so that a POSIX-sytle time zone string
+# can appear in the Dhaka binary file and for the benefit of old glibc
+# reimplementations of the time zone software that mishandle permanent DST.
+# A change will be required once the end date is known.
