This happened to me today, too. This morning I restarted my phone for unrelated reasons, but after I restarted it I saw that the time was incorrect. I restarted my phone again to fix the problem, and at first the time was correct, but within 10 minutes it became wrong again. I am in Pacific daylight time, but my phone kept setting itself to Alaska time, which is 1 hour off. I restarted my phone a third time and so far it is holding the correct time zone setting, but now I don't trust it. Please tell me how to fix this, as I certainly do not want to wake up late because my alarm clock goes off for the wrong time zone.
