  • Publication number: 20200025941
    Abstract: An electronic device includes a receiver, a processor, and a communication unit. Via the communication unit from an external device, the processor receives altitude information on each of altitudes obtained at intervals of a first period, at intervals of a second period that is longer than the first period, and individually receives altitude information on an altitude obtained not at intervals of the first period. In response to receiving the altitude obtained not at intervals of the first period, the processor performs positioning at the receiving timing. Based on obtainment timings of the altitudes received at intervals of the second period and an obtainment timing of the altitude received individually, the processor correlates the altitudes received at intervals of the second period and the altitude received individually with positioning results of the positioning such that the obtainment timings correspond to positioning timings of the positioning results.

  • Patent number: 10429799
    Abstract: The analog electronic timepiece includes rotatable plural hands, a current position acquisition unit, a processor and a counting unit. The current position acquisition unit acquires a current position and stores local time settings therein. The local time settings include time zones and daylight saving time implementation information in each area. The processor rotates the plural hands, reads and acquires a local time setting corresponding to the acquired current position from the current position acquisition unit, and selects and sets a time zone. The counting unit counts the local time, based on a later action which the processor performs either the acquired local time setting or the set time zone. The processor controls at least one of the plural hands to display a local time determination result as to whether the counted local time is based on the acquired local time setting in correspondence to the current position.
