I had the same problem on a recent trip to Hawaii; all appointment times in the calendar were 3 hrs off. I don't see the setting the other poster mentions, but from the Evo desktop, under Menu, Settings, Date & Time, the Automatic choice is checked by default. Once Automatic is unchecked,you can set the date & time. I did not find this while in Hawaii, so I have not verified that this solves the calendar time shift problem, but looks like it should. Can someone who travels please verify?
