Abstract

An electronic timepiece including: a clocking unit which counts current date and time; a summer time application unit which applies summer time information corresponding to positional information to the date and time counted by the clocking unit; a radio wave reception unit which receives radio waves including summer time implementation information of a predetermined area; a summer time information acquisition unit which acquires the summer time implementation information from the received radio waves; a storage unit in which a summer time implementation rule of each area in the world is stored in advance; and an information selection unit which selects, as the summer time information, one of the summer time implementation information and the summer time implementation rule corresponding to a current position on the basis of the current position and the summer time implementation information.

First claim

What is claimed is:

1 . An electronic timepiece comprising:
a clocking unit which counts current date and time; a summer time application unit which applies summer time information corresponding to positional information to the date and time counted by the clocking unit; a radio wave reception unit which receives radio waves including summer time implementation information of a predetermined area; a summer time information acquisition unit which acquires the summer time implementation information from the received radio waves; a storage unit in which a summer time implementation rule of each area in the world is stored in advance; and an information selection unit which selects, as the summer time information, one of the summer time implementation information and the summer time implementation rule corresponding to a current position on the basis of the current position and the summer time implementation information acquired by the summer time information acquisition unit, wherein the summer time application unit applies the one selected as the summer time information to the date and time.

2 . The electronic timepiece according to claim 1 , wherein priority information is stored in the storage unit for each of areas which are divided in advance, the priority information indicating whether to select the summer time implementation information with priority over the summer time implementation rule in an area, and the summertime implementation information being included in the radio waves which are receivable by the radio wave reception unit in the area.

3 . The electronic timepiece according to claim 2 , wherein the priority information is determined to indicate selecting the summer time implementation information with priority for an area where summer time is implemented during a same period of time as a period of time indicated by the summer time implementation information included in the radio waves which are receivable by the radio wave reception unit.

4 . The electronic timepiece according to claim 2 , further comprising an operation unit which receives an operation for changing the priority information in the storage unit.

5 . The electronic timepiece according to claim 3 , further comprising an operation unit which receives an operation for changing the priority information in the storage unit.

6 . The electronic timepiece according to claim 1 , further comprising a positioning unit which measures the current position, wherein the information selection unit newly selects the summer time information on the basis of the current position when the positioning unit measures the current position.

7 . The electronic timepiece according to claim 2 , further comprising a positioning unit which measures the current position, wherein the information selection unit newly selects the summer time information on the basis of the current position when the positioning unit measures the current position.

8 . The electronic timepiece according to claim 3 , further comprising a positioning unit which measures the current position, wherein the information selection unit newly selects the summer time information on the basis of the current position when the positioning unit measures the current position.

9 . The electronic timepiece according to claim 4 , further comprising a positioning unit which measures the current position, wherein the information selection unit newly selects the summer time information on the basis of the current position when the positioning unit measures the current position.

10 . The electronic timepiece according to claim 5 , further comprising a positioning unit which measures the current position, wherein the information selection unit newly selects the summer time information on the basis of the current position when the positioning unit measures the current position.
