Abstract

Abstract An electronic watch includes a "traveler's time" function which can be activated when a wearer leaves on a long trip, east or west by plane, boat or the like. This function will advance or retard the operation rate of the watch so that after a user-determined trip time has elapsed, the watch will display the actual local time at the arrival location, and the watch will resume operation at its normal rate. By glancing at the watch from time to time, a traveler can become accustomed gradually to a time change caused by his travel through different time zones so that the psychological effects of "jet lag" are minimized. The watch may also be used by a non-traveler to cause time to advance at a non-standard rate for other reasons. The watch includes a microprocessor (10), a quartz crystal (20) for providing a time standard, a display (30) for displaying the time, and a set of switches (40-90) for activating the watch's functions. The microprocessor includes a set of registers (145 to 160) for storing the departure, destination, operation rate, and traveler's times, and for controlling operation of the watch.
