PURPOSE:To improve failure in accurate time adjustment due to transmission delay, mistransmission, etc., in a conventional method for transmitting synchronous time information at a prescribed period from a station having a master clock to plural stations having slave clocks through a network in the case of adjusting time in a system connecting the master clock station to the slave clock stations through the network such as an LAN. CONSTITUTION:A time synchronizing pulse transmitting signal line 4 is newly disposed between the master clock station 1 and the slave clock stations 2, a time synchronizing pulse signal TP and time data TD for the pulse TP are respectively transmitted from the station 1 to the stations 2 through the signal line 4 and the network 3 at the prescribed period of the master clock 11 and the stations 2 execute the time adjustment by using the pulse TP and the data TD. |
