PURPOSE:To provide an automatic time-difference correction system wherein, as soon as a time-difference change line is passed, the time can be immediately adjusted automatically, it is possible to prevent that the adjustment of a time difference is forgotten or that the time difference is adjusted erroneously and the time conforming to every standard time region can be always known accurately. CONSTITUTION:An automatic time-difference correction system is provided with a clock 10 connected to a microcomputer 20, with a detection means 30 detecting the present position of an apparatus on which the clock 10 has been mounted and with a memory 40 in which a time-difference change line has been stored. In the automatic time-difference correction system, the time of the clock 10 is adjusted automatically by the microcomputer 20 on the basis of inputs from the detection means 30 and the memory 40. |
