PROBLEM TO BE SOLVED: To provide time signal clock which can generate an alarm when a user requires it even in a muting state. SOLUTION: When the time that a clocking means 2 clocks matches time set in a time setting means 8, an alarm control means 12 controls an alarm means 14 to generate an alarm. Normally, a muting control means 16 stops the alarm when it is dark around the clock. When arbitrary time is set in the time setting means 8, the muting control means 16 resets the stop of the alarm at the set arbitrary time. Consequently, the alarm is generated at the arbitrary time that the user sets even in the muting state. |
