Arizona Mountain. Standard Time. MST (UTC-7) 08:25:41 A.M. 24-Hour Clock Display. UTC is always displayed as a 24-hour clock. NIST promotes U.S. innovation and industrial competitiveness by advancing measurement science, standards, and technology in ways that enhance economic security and improve our quality of life.
An atomic clock is a clock that measures time by monitoring the resonant frequency of atoms. It is based on atoms having different energy levels. Electron states in an atom are associated with different energy levels, and in transitions between such states they interact with a very specific frequency of electromagnetic radiation.

- Why Use UTC – Not Tai?
Two components are used to determine Coordinated Universal Time (UTC): 1. International Atomic Time (TAI)is a time scale that uses the combined output of some 400 highly precise atomic clocks. It provides the exact speed at which our clocks tick. 2. Universal Time (UT1), also known as astronomical time, refers to the Earth's rotation. It is used to...
International Atomic Time is an extraordinarily precise means of time-keeping. Atomic clocksdeviate only 1 second in up to 100 million years. The secret to this impeccable precision is the correct measurement of the second as the base unit of modern time-keeping. The International System of Units (SI) defines one second as the time it takes a Cesiu...
The high level of precision achieved by using atomic clocks is both a blessing and a curse. On the one hand, accurate time-keeping is a necessity, for example for time-sensitive technology, such as modern air traffic control systems that rely on satellite navigation. On the other hand, TAI does not take into account the variations in Earth's rotati...
Atomic clocks are designed to measure the precise length of a second, the base unit of modern timekeeping. The International System of Units (SI) defines the second as the time it takes a caesium-133 atom in a precisely defined state to oscillate exactly: 9 billion, 192 million, 631 thousand, 770 times.
