Abstract
A time measurement device includes a power generator, secondary power source, current time countersand, receiver circuitfor receiving a time standard radio wave, time display meansfor displaying the current time, power detectorfor outputting a power detection signal when the power generatoris in a power generating state or when a voltage stored in the secondary power sourceis at a predetermined voltage value, operation mode switcherswitching, in response to the power detection signal, between a power saving mode in which time display is suspended and a standard mode in which time display is not suspended. The operation mode switchercauses the time display meansto display the current time based on the time information counted by the time countersandand the time information received by the receiver circuit in response to the device being switched from the power saving mode to the standard mode.
