Q: I am at Houston and sent me an email at 3/26/2006 5:25 PM and saved it as MSG. It displays at XP as 3/26/2006 6:25PM after the patch is applied (it's wrong as one Q article indicated). It also displays the same thing at Vista with Office 2007. But the historical data will be wrong after the patch is applied for machines prior to Vista.
A: The displayed timestamps in some folders, document properties (like creation or last modified times) from previous years will display one hour off. See http://blogs.msdn.com/mthree/archive/2007/02/20/your-questions-how-does-windows-handle-historical-events-with-daylight-saving-time-updates.aspx for more details. In order to preserve timestamps in documents that were created or modified during the extended DST period (the last three weeks in March and the last week in October) in previous years prior to applying the Windows OS DST updates for 2007, we recommend that you save or print important files as HTML, PDF or XPS (see http://www.microsoft.com/downloads/details.aspx?FamilyId=4D951911-3E7E-4AE6-B059-A2E79ED87041&displaylang=en for more details).
