• The UTC differentials associated with each city code are used to calculate World
Time Mode times, based on the time you set for any one of the World Time cities.
• 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 “Coordinated Universal Time”, 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.
• The above on indicators appear on the display in all modes.
• An on indicator on the display flashes while its corresponding alarm operation is
sounding.
• The snooze alarm on indicator flashes during the 5-minute intervals between
alarms.
