- How Is Tai Measured?
- 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...

Standard Time. MST (UTC-7) 06:44:41 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.
NIST-F1 is a cesium fountain clock, a type of atomic clock, in the National Institute of Standards and Technology (NIST) in Boulder, Colorado, and serves as the United States' primary time and frequency standard.
19. Juni 2019 · Atomic clocks combine a quartz crystal oscillator with an ensemble of atoms to achieve greater stability. NASA’s Deep Space Atomic Clock will be off by less than a nanosecond after four days and less than a microsecond (one millionth of a second) after 10 years. This is equivalent to being off by only one second every 10 million years.
