摘要：
Time is appropriately corrected without needlessly consuming power. In step S101 and step S102, a CPU of an electronic timepiece determines whether to correct a time measured by a timekeeping circuit. Then, when a determination is made to correct the time measured by the timekeeping circuit, in step S111 and step S112, the time measured by the timekeeping circuit is corrected on the basis of time information held by a wireless device.
