Abstract
PURPOSE:To provide an analogue display part with function of a world clock and, at the same time, attain interlocking and time transfer with each other between a digital display part and the analogue display part by carrying out process of time setting for the digital display part and the analogue display part chiefly on the digital display part. CONSTITUTION:Display of a digital display part is carried out through a digital display board 201, and, of an analogue display part through an indicator type display part 216, respectively. Output from a generation circuit 206 for reference frequency is input into a frequency dividing circuit 205, then a one second signal and a fast forwarding signal are outputted. A counter circuit 204 and a storing counter circuit 208, which is storing a time displayed in the indicator type display part, are set and the part 216 and the board 201 are corrected concurrently through a time correction circuit 223 and a reset circuit 224. Further, through an input circuit 227 for the difference in time, the circuit 221 makes the board 201 display the time of which the difference in time is corrected, and, in this time, the part 216 is displaying the present time. Then, the time of which the difference in time is corrected is displayed in the part 216, and the present time in the board 201, respectively, through manipulating a switch circuit 226 for transfer.
