+# From Nobutomo Nakano (2010-02-19):
+# We received a report from Bangladesh saying that the start/end of
+# Bangladesh DST is incorrect. Currently we have only the Bengali version
+# of the official mail from BTRC which describes the following:
+#
+# "From 2010 each year when local standard time is about to reach
+# March 31 at 10:59:00 PM clocks are turned forward 1 hour (11:59:00 PM)
+# and when local daylight time is about to October 31 at 11:59:00 PM
+# clocks are turned backward 1 hour (10:59:00 PM)."
+#
+# So, DST will start/end 1 minute earlier.

+# is in Bengali; it does contain two "31"s as well as two "11.59"s and a "10.59"
+# which is consistent with the information provided by Nobutomo Nakano.
