Beschreibung
Zusammenfassung:	A satellite radio-controlled watch, including a receiving unit for receiving a satellite radio wave containing time information and position information; a storage unit for storing intersection point information indicating a position of an intersection point between a reference line along a great circle orthogonal to a specific great circle on the earth or a reference line along the specific great circle on the earth or a circle parallel to the great circle and a time zone boundary, and time difference division information on a wedge-shaped or belt-shaped area that is adjacent to the reference line and to which the intersection point belongs, and a time zone determination unit for determining a time zone, based on the position information, the intersection point information, and the time difference division information.
