An alarm sounds when the countdown reaches zero. � All of the operations in this section are performed in the Countdown Timer Mode, which you enter by pressing B.

World Time

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.
