ut1
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).

ut1
UT1 (Universal Time 1) is a timescale based on the rotation of the Earth in relation to distant celestial objects (stars and galaxies), but with certain adjustments to account for the variable rotation rate of the Earth. It is considered the most precise form of mean solar time and contains the same amount of seconds as International Atomic Time (TAI), but may differ from Coordinated Universal Time (UTC) due to the inclusion of leap seconds, which are used to adjust for Earth's slowing rotational speed.
