The meaning of ATOMIC CLOCK is a precision clock that depends for its operation on an electrical oscillator regulated by the natural vibration frequencies of an atomic system (such as a beam of cesium atoms).
atomic clock An extremely precise clock whose rate is controlled by the vibration of particular atoms or molecules whose frequency does not change. The standard kind of atomic clock, which is based on the vibrations of cesium atoms, gains or loses less than one second in three million years. ...
A clock that keeps time by the radiation frequency associated with a particular atomic reaction. Atomic clocks are used in official timekeeping.
Synonyms of clock 1 : a device other than a watch for indicating or measuring time commonly by means of hands moving on a dial broadly : any periodic system by which time is measured 2 : a registering device usually with a dial specifically : odometer 3 : time clock 4 : a ...
The rapid increase in accuracy and stability of optical atomic clocks compared to the caesium atomic clock as the primary standard of time and frequency asks for a future redefinition of the second in the International System of Units (SI). The status of the optical clocks based on either ...

Sundial, the earliest type of timekeeping device, which indicates the time of day by the position of the shadow of some object exposed to the sun’s rays. As the day progresses, the sun moves across the sky, causing the shadow of the object to move and i
