The Bangladesh cabinet cancelled its earlier decision to reintroduce daylight saving time from April 1st, 2010, considering its repercussion on people. Customers in Bangladesh can switch their computers to the “Central Asia Standard Time” time zone with the display name of “(UTC+06:00) Astana” which has a bias of UTC+6 as well and does not observe DST.
 
Microsoft's product teams have moved to a regular rhythm to update their products and services to reflect these time changes. For each update release, Microsoft accepts change requests at up to a few months prior to the release date.   Please refer to Microsoft's Policy in Response to DST/TZ Requests, providing recommendations in order to achieve more seamless transitions to new DST and time zones policies. We suggest that governments should provide the following when considering changing DST or making adjustments to time zones:

1.    Ample advance notice (1 year or more) of the planned change.
2.    Official published confirmation of planned changes to DST or time zones.
3.    Concentrated efforts on promoting the change to the affected citizens.
 
Important notes for governments:
 
    * Please refer to Microsoft's Policy in Response to DST/TZ Requests. It's important for countries and territories to work towards seamless transitions to new DST and time zones policies, providing ample advance notice (of a year or more) with published confirmation of planned changes.
