Digital Time and Date
Use the Timekeeping Mode to set and view a digital display of the current time and
date. When setting the digital time, you can also confi gure settings for summer time
(Daylight Saving Time or DST), your Home City code (the code for the city where you
normally use the watch), the 12/24-hour format.
This watch is preset with a number of city codes, each of which represents the time x
zone where that city is located. When setting the digital time, it is important that you
select the correct city code for your Home City. If your location is not included in the
preset city codes, select the preset city code that is in the same time zone as your
location.
Note that all of the times for the World Time Mode city codes (page E-18) are x
displayed in accordance with the digital time and date settings you confi gure in the
Timekeeping Mode.
After you correctly set your Home City time and date, you can set the watch up for x
timekeeping with a different city code simply by changing the Home City code in the
Timekeeping Mode.

World Time
All World Time Mode times are calculated from the current Home City time in the x
Timekeeping Mode using UTC time differential values.
The UTC differential is a value that indicates the time difference between a x
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 x
world-wide scientifi c 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.
