Abstract
In a time synchronization system, a network controller sets transmission distance information on a transmission distance through which an optical signal is transmitted between transmission and receiving servers via a queueless network to a receiving server, based on network topology information. The transmitting server transmits a transmitting side current time synchronized with a reference time to the receiving servervia the queueless network. The receiving server calculates a transmission delay time between the transmission and receiving servers by dividing the transmission distance, which is based on the set transmission distance information, by light speed in the queueless network. A receiving side current time is calculated by adding the transmission delay time to the transmitting side current time.
