<P>PROBLEM TO BE SOLVED: To provide a time correction information output device, an automatic time correction timepiece, a time server, and an electronic apparatus, with enhanced accuracy by adding position-based time correction to time correction of a radio wave timepiece. <P>SOLUTION: This device comprises a reception part 2 for receiving a standard time radio wave having time information, a time information acquisition part 3 for outputting time data corresponding to the time information in the radio wave received by the reception part 2, a position information input part 4 for therein inputting position information, and a position information processing part 5 for calculating a distance between two points based on a first group of position data, with the inputted first group of position data referred to as the first group of position data, and on a second group of position data which are position information on a transmission base station for transmitting a previously stored standard time radio wave to calculate a time correction amount corresponding to the distance. Further, this device comprises a time correction processing part 6 for correcting a reference clock and calendar data for the timepiece by using the time correction amount calculated by the processing part 5 and the time data outputted from the acquisition part 3, and outputting them as corrected time data. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
