Alarm

World Time

The seconds count of the World Time is synchronized with the seconds count of the Timekeeping Mode.

All World Time Mode times are calculated from the current Home City time in the Timekeeping Mode using UTC time differential values.

The UTC differential is a value that indicates the time difference between a reference point in Greenwich, England and the time zone where a city is located.

The letters “UTC” is the abbreviation for “Universal Time Coordinated”, which 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.

Illumination Precautions

An LED (light-emitting diode) illuminates the display for easy reading in the dark. In any mode (except when a setting screen is on the display), press Lto turn on illumination for about two seconds.

Frequent use of illumination runs down the battery.
