Electronic timepiece, control method, and non-transitory recording medium

A control method comprising:

• keeping time;
• displaying time;
• controlling clock time to be kept in the keeping of the time and display time to be displayed in the displaying of the time;
• receiving standard waves and obtaining time information;
• calibrating the clock time based on the time information indicated by the received standard waves;
• and
• controlling the display time based on whether daylight-saving-time (DST) application rule information and a specific-region DST application rule information satisfy a predetermined condition, wherein the DST application rule information is associated with standard-wave transmitting station information indicating a station transmitting the received standard waves, in information that includes the DST application rule information for each region and the standard-wave transmitting station information in association with each other, the standard-wave transmitting station information indicating each station transmitting standard waves receivable in the region, and the specific-region DST application rule information indicates DST application rules for a specific region.

A non-transitory recording medium storing a computer-readable program thereon, the program causing a computer to function as:

• a storage that stores local time information and specific-region daylight-saving-time (DST) application rule information, wherein the local time information includes DST application rule information for each region and standard-wave transmitting station information in association with each other, the standard-wave transmitting station information indicating each station transmitting standard waves receivable in the region, and the specific-region DST application rule information indicates DST application rules for a specific region;
• a clock that keeps time;
• a display that displays time;
• a controller that controls clock time to be kept by the clock and display time to be displayed on the display;
• and
• a standard wave receiver that receives the standard waves and obtains time information, wherein
• the controller
• calibrates the clock time based on the time information indicated by the standard waves received by the standard wave receiver, and
• controls the display time based on whether the DST application rule information and the specific-region DST application rule information satisfy a predetermined condition, wherein the DST application rule information is associated with the standard-wave transmitting station information in the local time information and the standard-wave transmitting station information indicates a station transmitting the standard waves received by the standard wave receiver.
