I noticed that time on my iPad 3G 64GB is slightly different (less than a minute) from time of my MacBook Pro, that itself is different from time of my iPhone.

How does iPad update it's clock?

Thanks in advance,

Your MBP updates time from a time server over the internet. The iPhone sets the time using the cell phone system. My AT&T iPhone is always 1 minute behind my MBP.

I think that the iPad syncs time with iTunes or through the WiFi network. My iPad which syncs to my MBP and uses WiFi from an Apple AirPort Extreme has the same exact time as my MBP, down to the second (they switch minutes simultaneously). I might be wrong on this point, so if someone knows something more, I will stand corrected.

my iPhone and iPad are a couple of seconds off from each other...there have been some weird bugs i've ran across that made both stay the same distance apart, but be 4 minutes slower than all my other clocks and my wife's iPhone and my daughter's iPhone... go figure, but the iPad and my iPhone are always in sync (within a couple of seconds) with each other...
