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 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, and traveler's times, and for controlling operation of the watch.

A method enables the prediction of the likely alertness level of an individual at a given point in time based upon the analysis of certain biological and other parameters associated with the individual subject including, circadian phase of the biological clock, accumulated acute or chronic sleep deprivation, shift commencement and termination time, time of last sleep, environmental light, etc. Among other advantages, the method facilitates the creation of bio-compatible schedules for shift workers by providing an accurate model of the likely alertness level of the individual on a specific schedule.

A timepiece for continuously calculating and displaying the actual biological time of day of an individual. After an initial biological time of day is entered, the timepiece runs at a pre-determined rate corresponding to the rate at which time would progress in a free-running circadian clock for the individual. When the individual is exposed to clock-altering stimuli, such as bright light, the timepiece computes a new operation rate based upon the relative effects of the clock-altering stimuli as determined by a phase response curve for the individual. By combining information concerning the presence or absence of clock-altering stimuli with information concerning the effects of that stimuli, the watch is able compute and continuously display the individual's accurate biological time.

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.
