A hotfix is available to update the Daylight Saving Time for Bangladesh for Windows XP-based, Windows Server 2003-based, Windows Vista-based, Windows Server 2008-based, Windows 7-based and Windows Server 2008 R2-based computers
According to an announcement from the Bangladesh government, the Bangladesh cabinet decided to advance Bangladesh Standard Time by one hour from 23:00:00 June 19th, 2009 to save electricity during evening peak hours. No DST end date has been announced at the time of this release. There was no DST for Bangladesh prior to this announcement. This hotfix adds a new (GMT +06:00) Dhaka time zone with the following DST settings:
- DST starts at 23:00:00 on June 19th, 2009 and will continue until end of 2009
- Bias will change to UTC+7 in 2010 with no DST
Note: When the Bangladesh government announces the final DST policy, a further update will be required.
