PURPOSE:To perform time synchronization between each station with high accuracy. CONSTITUTION:A station 1 sets a time synchronizing frame, and transmits the time synchronizing frame to another station. A lag time measuring part 3 measures a time until the time synchronizing frame is transmitted to another station after a transmission request is issued as lag time, and such time is set on a time correction frame as a time correction value. The frame is transmitted to another station 1, and the time synchronizing frame is received, and the time is corrected. Thence, the time is corrected by receiving the correction frame and adding it on the correction of the time. |
