In case an area location of a portable terminal apparatus (10) has changed with the movement of the portable terminal apparatus (10) thus causing a time difference in the area location of the portable terminal apparatus (10) before and after the movement, the time controller (24) obtains time difference information form a time difference information database (34), adds/subtracts the obtained time difference information to/from a reference time of a timekeeping section (18) to automatically calculate the time corresponding to the area location of the portable terminal apparatus (10) after movement and displays the time on the display section (26).

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.

Abstract: A portable processing device, such as a laptop computer, includes a time-of-day clock that is dynamically adjusted based upon occurrences of travel among different time zones. An itinerary is stored as a travel schedule of departure and arrival information and is used to identify anticipated multi-zone travel.

Abstract: For time zone conversion an analog radio clock is provided with a switch device (31), preferably a rotary switch, through which an hour correction value is continuously provided. The UTC-Time received from a time signal transmitter is corrected corresponding to this hour value in a differential establishing step (33). Additionally the analog radio clock is provided with the possibility, to decode whether the time signal transmitter transmitted information is at that instant in a summer or winter time period. Insofar as summer time is decoded, the correction value from the switch device (31) is automatically increased by a value of 1. The output signal from the differential establishing step (33) is employed for step control of the analog radio clock, which thus automatically indicates the instantaneous correct local time upon corresponding setting of the switch device (31).

Abstract: A time-keeping section is programmed in such a manner that a predetermined number of virtual particles are caused to reciprocatively move between two virtual space regions successively, and the time-keeping section can sequentially keep time with accuracy using, as a basic time unit, a time required for the predetermined number of virtual particles to make a single travel from one of the space regions to the other space region. With the time values yielded by the time-keeping section, it is allowed to accurately accumulate the basic time unit over a preset time period (e.g., time data for 1,000 years). By incorporating such a time measuring device in each selected computer, accurate common time can be set for shared use among computers connected in a network and also with a computer loaded in an artificial satellite operating far from the earth. In addition, communication among the computers and remote control of any of the computers can be performed very smoothly.

Abstract: An electronic Personal Information Manager (PIM) including a calendar/scheduling system with an EarthTime.TM. module is described. In operation, the system tracks different types of times: "local" time, "home" time, and "remote" time. Home time is the time zone of where the user typically spends most of his or her time; this is usually the time zone for the user's home office. Local time is the time for the locality where the user is located physically at any particular instance in time. "Remote" time represents the time zones of the other individuals (i.e., other than the user). The system may show events and appointments in the user's own "local" time (or other user-selected type of time), regardless of where the user is presently located. Using these three types of time (i.e., "local" time, "home" time, and "remote" time), the system provides improved interface and methods for scheduling and managing activities, such a phone conference, across multiple time zones.
