Disclosed is a method of synchronizing the time-of-day (TOD) clocks in the individual processors of a multiprocessor complex with a switched- star topology. The method integrates a time reference within the switching system, which broadcasts the reference signal to the processors over dedicated fiber-optic links. This is an alternative to providing a separate time reference with its own network of fiber-optic links.
