When we think of time, we think of clock time. Action all around the world is synchronized by clock time, starting with train schedules, worldwide plane schedules, navigation, astronomy, worldwide telecommunication, etc. These depend completely on accurate timing. The accuracy standards of time keeping devices have been increasing rapidly due to the demands for more and more accurate timing for space communication, navigation, astronomy, etc. Rather than use mechanical clocks, we are relying nowadays on “atomic clocks.” This is not a clock in the usual sense but a device that uses the very stable oscillation of the cesium atoms as a standard for timekeeping.
