PROBLEM TO BE SOLVED: To improve operability of a time adjustment device by informing a user of mistake in time adjustment and making the user aware of a shift from the measured time. SOLUTION: A broadcast signal receiving means receives a broadcast signal from a station and takes out and detects a time signal. When a time signal is detected, a time adjustment means adjusts time with the time measured by a clock means. An information means watches whether or not the time signal is detected with the broadcast signal receiving means in the predicted time period of the time signal and informs of the state of time signal detection at the predicted time of coming of the time signal. Since the measured time is adjusted to the detected time signal and the time signal detection state is informed, the user can notice whether the time adjustment of the time adjustment device is being performed or not. |
