Timekeeping
•
Resetting the seconds to
while the current count is in the range of 30 to 59 causes
the minutes to be increased by 1. In the range of 00 to 29, the seconds are reset to
without changing the minutes.
•
The year can be set in the range of 2000 to 2099.
•
The watch’s built-in full automatic calendar makes allowances for different month
lengths and leap years. Once you set the date, there should be no reason to change
it except after you have the watch’s battery replaced.
World Time
All World Time Mode times are calculated from the current Home City time in the
Timekeeping Mode using UTC time differential values.
•
The seconds count of the World Time is synchronized with the seconds count of the
Timekeeping Mode.
•
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.
