If I create a calendar event in my Google Apps account (or in Outlook that's connected to my Google Apps account w/ the Google Apps Sync Tool) I get two possible behaviors on my Windows Mobile HTC smart phone:
1. The start and stop times match if I create the event before March 14 (the Daylight Savings Time effective date).
2. The start and stop times are off by one hour if I create the event after March 14.
