摘要
PROBLEM TO BE SOLVED: To synchronize time between data processors by correcting a transmission delay time between communication devices and an internal delay time of the data processor by use of a synchronous signal of the communication device without using a device receiving a time signal.;SOLUTION: In this time synchronization method, the first synchronous communication device transmits the synchronous signal (S101), and the second synchronous communication device receives the synchronous signal (S102). The second synchronous communication device measures a time after receiving the synchronous signal (S103). The first synchronous communication device transmits time t1 when transmitting the synchronous signal (S104). The second synchronous communication device receives the time t1 (S105), ends the measurement of the time (S106), and adds the measured time to the time t1 to calculate present time (S107). The second synchronous communication device sets the calculated present time to be synchronized with the first synchronous communication device.;COPYRIGHT: (C)2007,JPO&INPIT
