Timekeeping
•
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 normally should be no reason
to change it. Note, however, that if the watch is left uncharged for about one week
after battery power drops to Level 3, the current time and all other settings return to
their initial factory defaults.
•
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 time zones in the Timekeeping Mode and World Time Mode
is calculated in accordance with the Coordinated Universal Time (UTC) offset of
each zone, based on your Home Time Zone 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.
