Abstract: When an operation button is pressed for three seconds, a second hand is reversed and fast-forwarded to the position of a currently set time difference. After the second hand stops, the second hand is moved stepwise to time difference display positions to continuously display time difference correction candidates. In this state, when the operation button is pressed, the second hand is caused to stop, and an hour hand is moved to the position of time determined in consideration of the time difference at which the second hand points. The time difference at which the second hand points is stored as a time difference set value, and an action mode is switched to a normal time display mode for time-difference time display based on the time difference set value.

Abstract: A mobile communications terminal and system in which a time displayed by the terminal can be corrected based on a reference time, while an intentional offset time can be established at the terminal without modification of the reference time itself. When a reference time (Tst) is 12:00, a user may purposely make a setting of, for example, 12:05 as a present time (RTC) generated by a time-generating portion. Accordingly, when the reference time (Tst) reaches 13:00, the present time (RTC) generated by the time-generating portion should be 13:05 unless deviation has occurred. Consequently, when the present time (RTC) is, for example, 13:04, correction is necessary. However, correction of the reference time (Tst) 13:00 itself fails to take into consideration the intentional five-minute advance, and so the reference time (Tst) of 13:00 is corrected with an added differential (&Dgr;t) of five minutes to 13:05.
