According to one embodiment, a GPS clocking device comprises a computing module, a storage module, a reading module, and a correction module. The computing module receives a GPS signal transmitted from a GPS satellite, and computes a receiving position of the GPS signal in the standard coordinate system of the GPS based on the GPS signal. The storage module stores position information which indicates areas different from each other in the employed standard time, and is represented by the standard coordinate system, and information on the time difference between the standard time of each area and standard time of the GPS. The reading module reads time-difference information corresponding to an area to which the receiving position computed by the computing module corresponds from the storage module. The correction module corrects the current time indicated by the time information included in the GPS signal by using the time-difference information.
