WebThe difference between mean and apparent solar time is known as the equation of time. This is usually expressed as a correction, never exceeding 16 minutes, that is added to or subtracted from apparent solar time to determine mean solar time. In the past, time was measured by observing stars with instruments such as photographic zenith tubes and Danjon astrolabes, and the passage of stars across defined lines would be timed with the observatory clock. Then, using the right ascension of the stars from a star catalog, the time when the star should have passed through the meridian of the observatory was computed, and a co…
