PROBLEM TO BE SOLVED: To eliminate the defects of generating an error concerning the time of all the slave nodes or stopping by correcting the present time of a timer to a standard time by time information service at each designated time based on time information frequency. SOLUTION: A time matching part 3 matches the time of the timer of each node of a router, a gate way, a time division multiplexer, etc., to a correct time at each previously designated time. A power source equipment and a switch 4 turn on and off the power source device and a power source supplying power for the whole node 2 including the part 3. A time information service device 6 sends voice service information and a signal sound to presently inform a caller of the time by dialing a previously fixed specific number. In this case, the time information frequency of a time information service is read and the present time of the timer is corrected to the standard time by the time information service at each designated time based on the time information frequency. |
