WebA mean solar day (what we normally measure as a "day") is the average time between local solar noons ("average" since this varies slightly over the year). Earth makes one rotation around its axis in a sidereal day; during that time it moves a short distance (about 1°) along its orbit around the Sun. WebUT1, a version of Universal Time, is the Local Mean Time at the prime meridian in Greenwich, London. It is one of the components used to calculate Coordinated …
