True time

原声例句
赖世雄高级美语

Perhaps the expression " Time is money" really is true: time spent with those whom we do not often see is indeed precious.

或许“时间就是金钱”这句话是千真万确的：花点时间陪陪我们难得见面的亲友，确实是每一刻都很珍贵。

Solar time

On a prograde planet like the Earth, the sidereal day is shorter than the solar day. At time 1, the Sun and a certain distant star are both overhead. At time 2, the planet has rotated 360° and the distant star is overhead again (1→2 = one sidereal day). But it is not until a little later, at time 3, that the Sun is overhead again (1→3 = one solar day). More simply, 1-2 is a complete rotation of the Earth, but because the revolution around the Sun affects the angle at which the Sun is seen from the Earth, 1-3 is how long it takes noon to return.
The equation of time—above the axis a sundial will appear fast relative to a clock showing local mean time, and below the axis a sundial will appear slow.
Sun and Moon, Nuremberg Chronicle, 1493

Solar time is a reckoning of the passage of time based on the Sun's position 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).
