Abstract
A plurality of processors are connected to one another through a transmission line to constitute a distributed data processing system. Each processor adds a processor identification code to the time of its own and broadcasts them as time data at fixed periods. Each processor receives the time data on the transmission line, judges whether or not the received time data is the time data of the processor as the object of synchronization and sets the time data from the processor as the object of synchronization to the timer of its own system in order to synchronize the timers.
