  • Patent number: 9411318
    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.

  • Patent number: 6393263
    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.

  • Patent number: 4319350
    Abstract: An electronic watch comprises two passive electro-optic display devices one of which provides a digital display and the other of which provides an analog display. In one operational mode, the analog display device displays the local time while the digital display device furnishes other information such as the days of the week and the dates, for example. In another operational mode, which is selected by means of a push-button, the analog display device comprises only one activated segment (constituted or formed of a ray) which is consequently visible, to indicate opposite a scale of the time zones which time zone is actually selected, the digital display device then indicating the time of the selected time zone. The selection of the time zone which is displayed by the digital display device is effected by means of another push-button.

  • Patent number: 4313186
    Abstract: An electronic timepiece with a digital display includes a timekeeping circuit which stores the present time in a specific geographical region A, a keyboard adapted to introduce a time difference between two geographical regions A and B, and a calculation circuit which executes a time zone change operation by means of the contents of the timekeeping circuit and the time difference introduced via the keyboard, thereby loading the timekeeping circuit with the results of the time zone change operation instead of the previously stored horological information. When one desires to obtain a time zone change in another region C, the time difference is introduced into the timekeeping circuit storing the present time in the time zone B.
