I got mine working without applying any fixes. Here's what I did:

In iGo, under Regional Settings, Time Settings, Set Time Zone to Eastern US and uncheck both boxes above. Then exit iGo, and go to Settings, System, Clock and Alarms, and make sure your Home is set to Eastern. Lastly, go to phone, settings, services, time synchronization, and make sure the box is checked for auto sync, and click update now.

I think I had to do that twice with a reboot in the middle, but I have not had a problem since (coming up on a week of regular use).
