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. Best regards, -Nakano
