Abstract A multimode electronic timepiece includes a display, a plurality of manually actuated switches, and an integrated circuit having memory locations. The integrated circuit is programmed to keep time and to provide a plurality of modes, including time-of-day and at least one alternate time zone. The integrated circuit is further programmed to permit an operator of the multimode electronic timepiece to set the time-of-day and the alternate time zone in response to actuation of selected switches, and to store the time-of-day and the alternate time zone data in the memory locations. The improvement comprises a flag means which will copy the contents of the memory location storing the time-of-day data to the memory location for the alternate time zone data when the time-of-day has been set and the alternate time zone has not been set by the operator.

An improved multimode electronic timepiece of the type having a display, a plurality of manually actuated switches, and an integrated circuit having memory locations, the integrated circuit being programmed to keep time, to provide a plurality of modes, including time-of-day and at least one alternate time zone, to permit an operator of the timepiece to set the time-of-day and the alternate time zone in response to actuation of selected switches, and to store the time-of-day and the alternate time zone data in the memory locations, wherein the improvement comprises: flag means for copying the contents of the memory location storing the time-of-day data to the memory location for the alternate time zone data when the time-of-day has been set and the alternate time zone has not been set by the operator, the copied contents in the memory location for the alternate time zone data being displayed on the display in response to actuation of a selected switch and being changed in further response to actuation of selected switches, the flag means including a flag bit set in one of the memory locations of the integrated circuit, the value of the flag bit being dependent upon whether or not the operator has set the alternate time zone.
