Abstract: An electronic timepiece includes a radio wave receiver, a communication unit, a memory and a processor. The radio wave receiver receives radio waves from positioning satellites. The communication unit communicates with an external device. The memory stores a program and predicted positional information on the positioning satellites. Based on the program stored in the memory, the processor shifts the timepiece between a normal operation state and a power saving state in which operation of the timepiece is restricted, depending on a status of the timepiece. In response to an elapsed time from a valid period of the predicted positional information exceeding a predetermined reference time during the power saving state, the processor causes the communication unit to receive updated data of the predicted positional information and other information from the external device when shifting the timepiece from the power saving state to the normal operation state.

Abstract: A wireless communication apparatus includes (i) a wireless communicator capable of broadcasting an extended advertising packet having a large transmittable capacity and a compatible advertising packet having a transmittable capacity smaller than the extended advertising packet, and (ii) a processor. The wireless communicator periodically broadcasts the extended advertising packet based on a command from the processor. The processor sets offset information for acquiring of a time at which the extended advertising packet is receivable in an offset notification packet that is the compatible advertising packet, and broadcasts the offset notification packet via the wireless communicator. The offset information is set based on a transmission timing of the offset notification packet and a transmission timing of the extended advertising packet.

Abstract: 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.
