Abstract
A method and system for synchronizing two clocks of a first and second device. Successive synchronization messages are sent from the first device to the second device. Each synchronization message has a timestamp. Each message is received at the second device and the period between successive timestamps is determined. The period of the second clock of the second device is also determined. The period between timestamps is compared with the period of the second clock of the second device. The period of said second clock is adjusted based upon the comparison.
