    The problem as it is; Have an iPhone 5, bought one month after launch, and now the last two days the system time, i.e the clock and its dependencies such as timer and alarm are berserk. When the screen is turned on the clock will update if I go to time settings and turn automatic time on / off. As soon as i turn the screen of via the power button the clock freezes and won't update again unless I repeat the procedure. I've tried hard restart, restore, clean restore without backing it up again and still the same problem. The phone it self is in mint condition, no drops and such just the ordinary scuffing that occurs. The phone being out of warranty now creates problems.

    Called Apple service here in Sweden today and they told me to contact my service provider because I bought it via them. And the service provider told me contact Apple :D. So.. no working alarm, iMessage having problems with incorrent time and so on.. What could possibly be wrong? Asked my friend who knows about phones and he told me about some "memory" the phone has and that it could have given up? Any ideas? :confused:

    Do you know anyone with an iPhone 5 on the same carrier you're on? I'd be curious to know if their phone exhibits the same behavior at the same location.

    It would seem to me that this would be a carrier issue in most cases since cell phones usually get the time from local cell towers. That is definitely an odd problem. Does the time correct itself if you're in a different geographic location? I'm wondering if there's a problem with one or more cell towers in your area. If your phone is set to keep the time automatically, it should not be capable of losing the correct time unless a nearby cell tower is reporting the wrong time.

    Thanks for your reply. I don't think it's a carrier issue, the same thing happens while I'm on wifi and also at other locations.

    Even when you're on Wi-Fi, if the cellular radio is on, the iPhone should be polling for the time from a cell tower, not from the wireless router you're connected to. If the cellular radio is off but Wi-Fi is on, the clock will continue progressing on its own; but the iPhone will not actually poll for time discrepancies with its clock until it reconnects to the cellular network. At least that is my understanding. I could be wrong, though.

    How long does it typically take for the iPhone's clock to become out of sync after the time is initially correct? Minutes? Hours? Days? One thing you could try is this -- once the time is known to be correct on the phone, put the phone into Airplane Mode for an extended period of time and see if the phone still goes out of sync with the actual time. If that happens, then I'd suspect you have a hardware or software issue with either the phone or iOS. If the time does not go out of sync with the device in Airplane Mode, I think your device is getting faulty time information from your carrier's cell towers.

    Another thing to try would be to see if a friend on your same carrier with the same device and version of iOS also has the same problem.
