Abstract
PURPOSE:To prevent the accumulation of the difference between the displayed time and the actual time so that the always correct time can be displayed by correcting the displayed time automatically in accordance with time information. CONSTITUTION:A broadcasting station transmits the broadcast radio waves including the prescribed time information which is received by a receiver 22. A detection circuit 23 outputs the prescribed detection signal upon detection of the time information from the output of the receiver 22. A comparator circuit 24 compares the data (displayed 4 time) stored in a register 3 at this time and the prescribed reference value outputted by a reference value generating circuit 25. A correction circuit 26 outputs a correction signal to a counter 2 in accordance with the output of the circuit 24. For example, said circuit emits the correction signal to carry up the stored data at the next just time when said data is >=30min and to carry down the same to the previous just time when said data is <30min so that the time to be display 4 is corrected to the time such as prescribed just time. The accumulation of errors is thereby prevented and always the exact time is displayed.
