Thanks to Lourdes, with a note of the Optional Fix-it that is now available for Daylight Saving Time changes in Bangladesh this year.
As reported in the Bangladesh Government’s Gazette, Bangladesh has announced the introduction of Daylight Saving Time (DST). The start of DST for 2009 is on June 19th at 11:00
Microsoft has produced an automated workaround (called a fix-it) to implement the DST Start time change for Windows XP, Windows Server 2003, Windows Vista and Windows Server 2008. The Fix it solution is a MSI file so it is deployed as any other MSI based software package.
If interested in downloading this workaround please refer to KB972423 titled:”An optional update is available to update the Daylight Saving Time for Bangladesh for the year 2009 for Windows XP, Windows Server 2003, Windows Vista and Windows Server 2008 based computers”
For other Windows versions, please refer to KB 914387 “How to configure daylight saving time for Microsoft Windows operating systems” on how to update the time zone registry key.
Public service announcement: As noted in a prior post, our product teams are moving to a regular rhythm to update their products and services to reflect these time changes. (For each update release, Microsoft accepts change requests up to a few months prior to the release date.) But changes such as these – and without official notification – are difficult for sysadmins and IT professionals around the world to manage.
And here's my regular advice for governments: in support of these types of changes, we provide guidance and 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.
In addition – and this is important – we suggest that entities considering the changes implement changes at the next clock tick after 01:59:59 rather than at 23:59:59, 24:00:00 or 00:00:00. Making the change at midnight can impact daily systems, such as back ups, data pulls or other automated tasks.
