PROBLEM TO BE SOLVED: To automatically change time data in a slave machine even when time information such as a switching time between summer time and winter time is abnormal by performing a transmitting action at the time previously determined by a transmitting means and at the time based on a difference when the difference outputted from a computing means is a predetermined value or more. SOLUTION: When the time set in an ON/OFF means 5 matches the time in a main counter 8, the ON/OFF means 5 gives a receipt starting command to a receiving circuit 2 for starting receipt in the receiving circuit 2, and amplification, frequency-filter processing, and detection of radio waves provided from an antenna 1 is carried out, and from the receiving circuit 2, a detection result is outputted. From the detection result, a code determining means 3 determine respective codes 0, 1, P, and a data processing means 4 processes the data so as to produce time data, calendar data, and prediction information. In this process, if the data is not absent data, the data processing means 4 outputs the obtained data to the main counter 8 for updating its value, and at the same time, outputs a signal for the end of receipt to the ON/OFF means 5. |
