An electronic timepiece including: a clocking unit; a storage unit; a setting selection unit which selects, as summer time implementation information, the summer time implementation rule or user setting that specifies whether to implement summer time; and a local time acquisition unit which acquires local time at a predetermined point, wherein the local time acquisition unit includes: a movement determination unit which determines, when the setting selection unit selects the user setting, whether a previous point and a new point belong to a predetermined range in which local time counted at the previous point is equal to local time counted at the new point; and a summer time implementation information switching unit which acquires local time on the basis of the summer time implementation rule when the previous point and the new point do not belong to the predetermined range. |

1. An electronic timepiece comprising:
a clocking unit which counts current date and time; a storage unit in which a summer time implementation rule set for each area is stored; a setting selection unit which selects, as summer time implementation information, the summer time implementation rule or user setting that specifies whether to implement summer time; and a local time acquisition unit which acquires local time at a predetermined point by using the summer time implementation information, wherein the local time acquisition unit includes:
a movement determination unit which determines, when the setting selection unit selects the user setting, whether a previous point and a new point belong to a predetermined range in which local time counted at the previous point is equal to local time counted at the new point, the previous point being a position where local time is previously acquired, and the new point being a position where local time is to be newly acquired; anda summer time implementation information switching unit which acquires local time on the basis of the summer time implementation rule when the previous point and the new point do not belong to the predetermined range. |
