ABSTRACT:
A radio-controlled timepiece can adjust the time with a short reception process while also reducing the likelihood of incorrect adjustment. The radio-controlled timepiece has a reception control means31, time information updating means32, time adjustment storage means33, and time display means. The reception control means31has a simple time adjustment means330that is driven within a predetermined time of the last successful signal reception, and a normal time adjustment means320that is driven when this predetermined time has passed. The simple time adjustment means330has a pulse timing detection unit331, a offset calculation unit332, a offset evaluation unit333, and a seconds information adjustment unit334. The pulse timing detection unit331detects the reference timing, which is the timing of the rising edge or falling edge of rectangular wave pulses in the received time code. The offset calculation unit332calculates the difference between this reference timing and the timing of the seconds unit in the internally kept time. The offset evaluation unit333determines if this offset is within a tolerance range. The seconds information adjustment unit334adjusts the seconds unit of the internal time based on the offset if the offset is within the tolerance range.
