mean time

Time measured with reference to an imaginary sun that lies in the same plane as the Earth's equator and that the Earth orbits at a constant speed. Using this convention results in equal, 24-hour days throughout the year. If days were measured by the actual movement of the sun, they would vary slightly in length at different times of the year.
