ABSTRACT:
An international time indicating system is associated with a telephone for automatically displaying a specific time and date of a called place upon entering the international access code, called country code, and called area code if necessary. A called time and date are calculated via time zone offsets stored in system memory by determining the difference in time between a time zone of a local place of a caller and a time zone of a called place. The offsets are defined with respect to a reference time zone. The difference in time is then offset in order to determine the called time.
