Abstract:
A radio timepiece, including: a satellite radio wave receiver; a ground wave receiver; a memory; and a controller, wherein the controller performs area determination operation of determining whether a current position is located within a geographical range where the ground wave receiver is capable of acquiring notice information regarding implementation/non-implementation of the leap second adjustment, when the controller determines that the current position is located within the geographical range, the controller controls the ground wave receiver to acquire the notice information, the controller determines, with the notice information, whether the leap second adjustment is scheduled to be implemented at an implementation candidate timing of the leap second adjustment, and when the controller determines that the leap second adjustment is scheduled to be implemented, the controller changes the leap second correction information at or after the implementation candidate timing.
