Abstract
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.
