The time signal detection circuit that detects the time signal by receiving the radio frequency radiated from the device and the time measuring device that counts the time clock output from the specified frequency oscillator to generate the digital time information can be seen, and the time signal detection described above can be performed. The digital time information of the counting device is corrected by the time signal output from the circuit, and the corrected digital time information is set in the system timer for arithmetic control (Japanese Patent Laid-Open No. 57-130133). Japanese Patent Publication No. 179).

A first problem is that the basic clock generation circuit built into the personal computer manages the constant period of the oscillator, so that the error in the clock time continues to occur. .

The reason is that the built-in basic clock is
This is because the operator had to update the time information because there was some error.

The second problem is that if the power supply for driving the timepiece is cut off, the clock time will greatly differ.

The reason is that the backup power supply for a watch depends only on the battery.
