If anyone is still having a problem, here's what worked for me:

First, Click on you clock on your home page. Make sure your are set for your PROPER region, not what is giving you the right time as a workaround for this issue. For example, people on the East coast (NY) should be GMT-5 Eastern Time. If you choose anything else or manually adjust the time, your appointments will be off by an hour.

If your time is still not right, then go to the Comm Manager and press the bottom right soft key "Settings" then select "Phone". Choose "Services" on the bottom menu and select "Time Synchronization" then press "Get Settings". Make sure the "Time Sync with mobile network automatically" is Checked and press "Update Now"

That should do the trick.
