The laser-cooled atomic fountain clock is one of the world's most accurate clocks. If it ran for 60 million years, it would not be off by more than one second. Extremely accurate timing information is critical for such things as cell phone networks and Global Positioning Systems. The clock can be adjusted for time intervals shorter than one thousand trillionths of a second.
