of the applicable hand(s) and day.
• High-speed movement of the hands and day will continue until you press any button,
or until the moving hand(s) and day finish one complete cycle.
– One complete cycle for the hands is 24 hours.
– One complete cycle for the day is 31 days.
Timekeeping
• The date will change automatically when the current time reaches midnight. The
date change at the end of the month may take more time than normal.
• The current time for all city codes in the Timekeeping Mode is calculated in
accordance with Universal Time Coordinated (UTC*) data of each city, based on
your Home City time setting.
* UTC is the world-wide scientific standard of timekeeping. It is based upon
carefully maintained atomic (cesium) clocks that keep time accurately to within
microseconds. Leap seconds are added or subtracted as necessary to keep UTC
in sync with the Earth’s rotation. The reference point for UTC is Greenwich,
England.
