Bangladesh has announced it will introduce daylight saving time from this Friday. Bangladesh Starts Daylight Saving Time on June 19, 2009

Microsoft have introduced a "fixit" for this which I have installed. 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

What else do I need to do for myself and my staff to have things work properly in Zimbra. We use ZDesktop mainly but also ZCS with the full webclient. It is important for us as we are often booking calendar events with colleagues overseas.

Do I need to ask our international IT department to update the ZCS server as per Changing ZCS Time Zones - Zimbra :: Wiki ?

Do I need to do anything else to get Zdesktop to recognise the Bangladesh times properly?

Appreciate your help.
