It is defined as the main solar time at Mars' prime meridian.

它被定义为火星本初子午线上的主太阳时。

It gave mean solar time, mean sidereal time, equation of time, and could chart the phases of the moon.

表盘上不仅能显示平太阳时，还能显示平恒星时、时差，记录月相。

Globes even used to have the analemma printed on them to allow people to determine the difference between clock time and solar time based on the day of the year.

曾经的地球仪上面还会印上8字曲线，使人们能知道钟表时间和太阳时间的差距。

The equation of time, introduced by Ptolemy and later refined based on the work of Johannes Kepler, converts between apparent solar time and the mean time we've all come to rely on.

“均时差”概念，由托勒密发明后来由约翰尼斯·开普勒进行的改良，包含了太阳时间和平均时间的差距，是我们现在主要使用的时间概念。

But equally, it's useless to use solar time while tracking objects in space, because the region you're observing would shift between say, 10: 00 PM one night and 10: 00 PM the next night.

但同样，在跟踪太空中的物体时使用太阳时是没有用的，因为您观察的区域会在前一天晚上 10: 00 到第二天晚上 10: 00 之间变化。
