FAQs

Should I run this update even if I have Local Network Time and Network Time Zone enabled on my device?		Yes, regardless of the Network time & time zone setting on the devices, all users should install this update. Outlook depends on correct time zone information stored on the device.
If I use Exchange Server to schedule Outlook events, do the server and client PC need to be updated at the same time?		No, the client PC and Exchange server do not need to be updated at the same time. However, there is a certain sequence to the updating. Contact your IT department for more information. Most corporate end users will not be the ones who apply these updates. First: Exchange Server OS DST update Second: Client PC OS DST update Third: Exchange Server update Fourth: Outlook Tool for client PC Details about these updates available at Microsoft.com: Preparing for Daylight Saving Time changes in 2007
I have run the update and noticed that my appointments are 1 hour off. I set the system date as March 15 (3/15) and they are still running 1 hour off.		The Microsoft DST2007 update does two things: Change the DST rule. Add Tijuana, Baja California time zone for those in Mexico who are in PST zone, but don’t observe DST. Time shift during this period occurs because the DST rule update on the device happened correctly. However, the old rules embedded in the calendar events are not updated by the update. Synchronizing with Microsoft Outlook should resolve this correctly. Install to the PC the Windows OS DST update, and run Time zone update tool from Microsoft, then sync the device to correct the time shift.
