Apsis meaning

Solar time is a calculation of the passage of time based on the position of the Sun in the sky. The fundamental unit of solar time is the day. Two types of solar time are apparent solar time (sundial time) and mean solar time(clock time)

A leap second is a one-second adjustment that is occasionally applied to civil time Coordinated Universal Time to keep it close to the mean solar time at Greenwich, in spite of the Earth's rotation slowdown and irregularities.
