The clock on my iPhone is not accurate, despite the fact that I sync several times a day. Does the iPhone not use a time server? Rather than correct the clock manually on aregular basis, is there another way to ensure the time is correct?

    Is your clock set to set automatically? Go to Settings > General > Time & Date to check.

    It sounds like O2 doesn't provide an auto time sync . We have the option of using ATT's time servers or setting the time manually.

    It never synced with a time server, what it does for the automatic sync is get the time from the tower it is connected to. Some carriers do not provide this feature.

    I too have experienced the same problem. The 3Gs iPhone apparently does not get its time from the computer with which it is syncing. My computer, my GPS clock at home, and the GPS clock in my car all agree to the second.

    The iPhone is some 23 seconds behind.

    In the "Date and Time" preferences, I ensured that the "Set Automatically" was set to on, which I assume to mean setting to the network's time (I don't see a place to enter an NTP server). I set the "Set Automatically" to off and manually set some bogus time. I checked the Clock program. I went back and re-enabled the "Set Automatically" and checked the date program. The time, to the minute were set correctly but the seconds were not....

    O2 don't provide time sync.

    It's a bit naff that the iPhone doesn't sync with the Mac's clock when plugged in.

    Even my old Nokia 6310i with its steam-powered software could do that.

    Agreed - but it surely is the next best thing - checked against another radio clock it is exact.
