Perhaps only Apple, or someone that has worked for apple can tell us, 
but the system probably get the time from either WWV, WWVB and WWVH.

See; http://tf.nist.gov/

These are the official web sights of the US Government that maintain 
and broadcast the primary time signal for the everyones use. They us a 
Galleon Atomic Clock as the source for time keeping.
