MUCT is very similar in nature to how universal coordinated time or UTC works on earth.

火星协调通用时间在本质上与世界协调时间（UTC）在地球上的计算方式非常相似。

In order to account for the time difference, more recent rover missions have begun to use what is increasingly becoming known as Mars Universal Coordinated Time or MUCT.

为了解释时间差，最近的漫游者任务已经开始使用逐渐被称为火星协调通用时间（MUCT）的方法。

Much like how earth has a prime meridian marking for which universal coordinated time is based off of, Mars has a meridian that was first proposed way back in 1830 to be exact and is marked by a crater known as Airy-0.

就像地球上用来标记世界协调时间的本初子午线一样，火星上的子午线最早是在 1830 年提出的，精确地说，火星上有一个被称为 Air-0 的陨石坑。
