Abstract
A timekeeping device enables easily knowing how much playing time has passed and can automatically keep track of time added to compensate for stoppage time. The timekeeping device 1 has a input unit 2, a display unit 3, an alarm unit 5, and a control unit 4. The control unit 4 has a timekeeping unit 41 including a first timer 41A and a second timer 41B, a input control unit 42, a timekeeping control unit 43, a display control unit 44, a alarm control unit 45, and memory 46. The alarm unit 5 outputs a first alarm when the second timer 41B is keeping time and the time kept by the first timer 41A reaches a preset time setting. When the second timer is not keeping time and the time kept by the first timer reaches the preset time, the alarm unit 5 outputs the second alarm.
