The atomic clock is the standard timekeeping clock. The atomic clock is the most accurate and stable clock in the world. The atomic clock was first introduced in 1879.The first practical clock was made in 1949 at the National Institute of Standard and Technology which was formerly known as National Bureau of Standards.
The first clock was supposed to be less accurate than the one being used now. The atomic clock is based on the quartz clock. The atomic clock was commercialized in the 1950s. A small prototype was made in 2004 that was believed to become a consumer product.
National Institute of Standard and Technology introduced an atomic clock which is the most accurate clock made until now and was made in 2008. Atomic clock is used in Global Positioning Systems to match the accurate time. It has an onboard clock and is accurate up to fifty nanoseconds.
The time is effected due to the analog to digital conversion and may loose a fraction of a second. The atomic clock runs on atoms and electrons. There are three kinds of atomic clock which includes Hydrogen clocks, Rubidium and Cesium clocks. The clock does not contain any harmful substances neither it contains any radioactive material. Every year a standard daylight saving time is observed. It is experienced in many countries of the world mainly the United States, North America and European countries. The time will change on Sunday at 2am standard time. People in Hawaii will also experience the time shifting on Sunday the 14th of March
