<p>An electronic timepiece can easily acquire a leap second information reception time with minimal processor load. A first table groups leap second information reception times expressed by hour, minute, second, and day values into plural minute-second patterns of minute-second combinations that are common to plural hours, and relates numbers identifying these minute-second patterns to the day and hour values. The minute-second combinations are grouped by number in a second table. The number corresponding to the day and hour of the internal time is found from the first table (S1). A minute-second combination that is later than the internal time is found from the minute-second combinations corresponding to the acquired number (S2). And leap second reception time is calculated. If the resulting leap second reception time matches the internal time is determined (S9) . If the times match, the leap second information is received (S10, S11).</p> |
