IPhone Clock is wrong.

5 seconds slow? Unacceptable! Heresy! Recall!

Mine's 30 seconds slow. 😉

I doubt it connects to any server. Cell phone companies usually push the time over the air.

Don't know for sure, but I believe it is pulling the time from AT&T like a regular mobile.

yeah, I wonder if Apple shouldn't have it automatically update with the Apple server time clock like they do with the computer clock settings.

You're lucky.

Some people have said their clock is off by two minutes or more.

(Which yes, would indeed be intolerable in this day and age... especially with a lot of the population using cell phones as watches.)

well the problem is that the phones are GMS and they get there timing from the base stations. CDMA phones are GPS based and the time is very close to NIST. The base stations have to have lock on 7 satellites before it can go operational so the timing is very accurate.

ken444,

It gets time updates from whichever cell tower you are connected to.

Hope this helps,

Definitely an AT&T issue. I noticed my clock was correct, then suddenly, it was 2 hours and 3 minutes ahead all on its own! I checked my friend's AT&T Treo and the time was exactly the same as the iPhone. It eventually corrected itself.

Since when set to automatic, the iPhone gets the time from the local cell tower, if anyone is finding it in error by a degree that is problematic, simply set the time to manual in the Date and Time settings pane.
