Abstract
An electronic timepiece includes an obtaining circuit, a first processor and a second processor. The obtaining circuit obtains information on current time from outside. The first processor measures time. The second processor is connected to the obtaining circuit. The first processor obtains a synchronization signal corresponding to the current time, obtains the current time, which the second processor obtains from the obtaining circuit, and based on the current time and the synchronization signal, corrects the measuring time, which the first processor is measuring.
