iPhone time changes itself to 1 hour fast

Hi, I have had an 8GB iPhone for about 3 days. Everything had been ok except for the time and camera...so I took it to the store today and the Genius was unsure about the time problem but replaced my phone due to the camera issue hoping the time issue would also be resolved...(camera issue = photos have red center with green halo)

So I got home with the new phone and synced it. It was initially fine but I hooked it back up with the computer to add some pictures and when i did it immediatly added 1 hour to the time. Now I am unsure what to do as the first phone also did it for the Genius at the store (so we are pretty sure it is not just my computer since theirs did it too).

I now have all of the automatic time features turned off so that the time has to be set manually and it is still changing the time itself and adding 1 hour to the time.

I have all of the most current software updates (iTunes & iPhone)...since my phone is so new, I have not used the phone without the most current update.

Is anyone else having this problem and if so have you been able to resolve it and how? I would just hate to have to go back to the store again if it is something I can resolve myself...

Thanks for any and all help,
Rebecca
