It is the relation of the sun's hour angle to apparent time.
This will be the solar or apparent time, that is, the very time we require.
All the meridians centered at the pole, and the time there was the apparent time of every meridian on the globe.
The sun set this night at thirty minutes after eleven, apparent time.
The interval, by which apparent time differs from mean time, is called the equation of time.
We have, however, already seen that the apparent time of sunset would be the same from all stations if the earth were flat.
The sun-dial time marks "apparent time," the actual varying length of each day.
Mean TimeClocks, watches, etc., are made to measure equal units of time instead of the apparent time indicated by the sun.
When time is calculated by the stars it is called sidereal time; when by the sun, solar, or apparent time.
Apparent time called it one, real time said it was two hours after midnight.
