Abstract
A CPUA with a master clock sends a communication time count command to a CPUB whose time is to be compensated. In addition, the CPUA starts a timer. When the CPUA receives a reply to the communication time count command from the CPUB, the CPUA subtracts a predetermined time t that is from when the CPUB receives the communication count command until it sends a reply thereto from a count time T of the timer, so as to calculate the actual communication time between the CPUs. The CPUA notifies the CPUB whose time is to be compensated of the inter-CPU communication time and the time information counted according to the master clock. The CPUB compensates the time information counted by its internal clock according to the inter-CPU communication time and the time information received from the CPUA.
