<p class="category">火星上的计时方法</p>
</div>
<div class="content">
<p>
火星沿用了地球上秒、分钟以及小时，但是由于火星上一个太阳日的时间要比地球上的太阳日要长，因此火星上一天除了二十四个小时，还有一段的扩展时间，长度为 39 分 35.24409 秒。
</p>
<p>文字记录方法在每天的二十四小时内与地球的记录方法相同，超出二十四小时的部分采用“+时间”来记录，例如二十四小时后十三分钟二十六秒记作：+13:26.</p>
<p>
由于火星上一天的时间并不是 24 小时，这给时期的划分造成了一定的麻烦。
为了时间换算的方便，火星上相邻两个时区之间时差均为 1 个小时，这样的话，一个时区的所跨的经度就不再是 15°，而是 14.5987°。
火星上的本初子午线为穿过艾里-0 陨石坑的经线，并且火星上的经度均以东经表示，从东经 0°-东经 360°，并没有西经，因此，火星上的时区也是以本初子午线为起点，向东每隔 14.5987° 为一个时区。这样一来，火星上最先进入一天的时区为 24 区，即靠近 0 区左侧的时区。
