I had something strange happen to me today. Got my new Verizon iPhone yesterday, set it up, played with it a ton, and all was fine. Messed around with it some more today, no issues. I took my daughter to her soccer game and after the game I look at the lock screen and the date was August 31 and the time was 4am. I powered the phone off and on and the time and date were still wrong. Checked the settings and it is set to automatically set the time. Toggle that off and on and the time corrected itself and for the past 4 or 5 hours since then, it's been fine. Anyone else see anything like that?
