Time change issue on the 8X this morning

[gerrymad]

I looked at my 8X this morning and instead of it displaying 8:30 it was displaying 4:30. I looked at the settings and the phone seems to think I am (UTC-12:00) International Date Line West. I clicked on the date time setting to see if perhaps I had somehow changed it. It was set to automatic. If I turn off the automatic setting and pick Pacific Time then I am back to 8:30.If I turn automatic back on then I go back to being on the international date line. Is this an AT&T issue or has my phone had a problem with the time change?
