1. Universal Timenoun

   A measure of time that conforms, within a close approximation, to the mean diurnal rotation of the Earth and serves as the basis of civil timekeeping. Universal Time (UT1) is determined from observations of the stars, radio sources, and also from ranging observations of the moon and artificial Earth satellites. The scale determined directly from such observations is designated Universal Time Observed (UTO); it is slightly dependent on the place of observation. When UTO is corrected for the shift in longitude of the observing station caused by polar motion, the time scale UT1 is obtained. When an accuracy better than one second is not required, Universal Time can be used to mean Coordinated Universal Time.

1. Universal Time

   Universal Time (UT or UT1) is a time standard based on Earth's rotation. While originally it was mean solar time at 0° longitude, precise measurements of the Sun are difficult. Therefore, UT1 is computed from a measure of the Earth's angle with respect to the International Celestial Reference Frame (ICRF), called the Earth Rotation Angle (ERA, which serves as a modern replacement for Greenwich Mean Sidereal Time). UT1 is the same everywhere on Earth. UT1 is required to follow the relationship ERA = 2π(0.7790572732640 + 1.00273781191135448 · Tu) radianswhere Tu = (Julian UT1 date - 2451545.0).

1. universal time

   Universal Time (UT) is a time standard based on the Earth's rotation. It is a modern continuation of Greenwich Mean Time (GMT), i.e., the mean solar time on the Prime Meridian at Greenwich, London, UK. It is used in astronomy, navigation, and for the synchronization of clocks worldwide. UT is often subdivided into UT0, UT1, UT1R, and UT2, depending on the level of accuracy required. Hence, it is essentially a measure of time that sets the standard for clocks and time worldwide, allowing for synchronization and precise measurements.

1. Universal Time

   Universal Time is a time standard based on the rotation of the Earth. It is a modern continuation of Greenwich Mean Time, i.e., the mean solar time on the Prime Meridian at Greenwich, and GMT is sometimes used loosely as a synonym for UTC. In fact, the expression "Universal Time" is ambiguous, as there are several versions of it, the most commonly used being UTC and UT1. All of these versions of UT are based on the rotation of the Earth in relation to distant celestial objects, but with a scaling factor and other adjustments to make them closer to solar time.
