1. An electronic timepiece comprising:
- a clock circuit which counts a current date and time;
a memory storing a daylight saving time implementation rule set for each of a plurality of areas; and
a processor configured to execute a program stored in a memory to perform operations including;
selectively setting, as a daylight saving time application setting, one of (i) an automatic mode to implement or not implement daylight saving time according to the daylight saving time implementation rule set for each of the plurality of areas stored in the memory, and (ii) a manual mode to locally change the daylight saving time implementation rule for an area so as to manually implement or manually not implement daylight saving time in the area according to a user input; and
a local time acquisition process to acquire a local time at a current position, the local time acquisition process comprising;
determining whether the automatic mode or the manual mode is set as the daylight saving time application setting;
when the manual mode is set as the daylight saving time application setting;
determining whether the current position is within the same area as a previous position at which the local time was acquired, the area being a range in which the local time is the same;
changing the manual mode to the automatic mode when the current position is determined not to be within the same area as the previous position; and
acquiring the local time at the current position while applying the locally changed daylight saving time implementation rule in the manual mode so as to manually implement or manually not implement daylight saving time in the area according to the user input, when the current position is determined to be within the same area as the previous position; and
when the automatic mode is set as the daylight saving time application setting, acquiring the local time at the current position while implementing or not implementing daylight saving time in the automatic mode according to the daylight saving time implementation rule stored in the memory for the current position.

Abstract
An electronic timepiece includes a clocking unit, a storage unit, a setting selection unit which selects, as daylight saving time implementation information, daylight saving 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. 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 daylight saving time implementation information switching unit which acquires local time on the basis of the daylight saving time implementation rule when the previous point and the new point do not belong to the predetermined range.
