Title: 火星钟和其他新颖的模拟钟，使用地球标准秒

Abstract: We present analog clocks fitted to the Mars solar day. These clocks use the standard Earth-based second of the International System of Units (SI) as their operational unit of time, unlike current practice for Mars timekeeping. We discuss the importance of preserving the SI second. On this basis, we identify the two analog clocks most suitable for public use by a future Mars population. These are a 20-hour clock with a hand motion similar to that of the standard Earth clock, and a 24-hour clock with a novel "Martian" hand motion which strikes the hour when all 3 hands converge onto that hour mark on the dial. Both clocks have Earth-day equivalents to assist learning. We also present a 24-hour "SpaceClock", similar to the Martian clock but with no favored reference plane, hence equally readable from any viewing orientation. Show Chinese abstract

Abstract: 我们展示的是适合火星太阳日的模拟钟表。 这些钟表使用国际单位制(SI)的标准地球秒作为其时间操作单位，这与目前火星时间记录的做法不同。 我们讨论了保留SI秒的重要性。 在此基础上，我们确定了两种最适合未来火星人口使用的模拟钟表。 一种是20小时钟，其指针运动类似于标准地球钟；另一种是24小时钟，具有新颖的“火星”指针运动，在所有3根指针汇聚到表盘上该小时标记时敲击整点。 这两种钟表都有地球日的等效值以帮助学习。 我们还展示了一种24小时的“太空钟”，类似于火星钟，但没有偏好的参考平面，因此从任何观看方向都能同样读取。
