+ # From Alexander Krivenyshev (2009-12-24):
+ # According to Bangladesh newspaper "The Daily Star,"
+ # Bangladesh will change its clock back to Standard Time on Dec 31, 2009.
+ #
+ # Clock goes back 1-hr on Dec 31 night.

+ # "...The government yesterday decided to put the clock back by one hour
+ # on December 31 midnight and the new time will continue until March 31,
+ # 2010 midnight. The decision came at a cabinet meeting at the Prime
+ # Minister's Office last night..."
+ 
+ # From Danvin Ruangchan (2009-12-24):
+ # ...the news mentions DST will be turned off again 7 months after March
+ # 31st on Oct 31, 2010.
+ 
+ # From Arthur David Olson (2009-12-26):
+ # Indeed, "The government will advance again the Banglasdesh Standard
+ # Time by one one hour on March 31 next year by enforcing the Daylight
+ # Saving Time (DST) for seven months. It will continue till October 31
+ # until further notice." I take that last sentence as the
+ # establishment of a rule.
