Daylight Saving Time, or DST, is a system for uniformly advancing clocks.

夏令时，简称 DST，是种统提前时钟的系统。

All the information of each of those clocks comes up here where we have a computer system that analyzes the whole ensemble of clocks, about every 100 seconds.

每个时钟的所有信息都在这里，我们有个计算机系统来分析整个时钟集合，时隔大约是 100 秒。

I don't know the state of that field right now, but I imagine that if you're trying to distribute a clock across any appreciable size computational system, you want to use light.

我不知道那个领域的当前状况，但我认为如果你试图在个具有模的计算系统中分布时钟，你会想要使用光。

So we have this biological system, this clock, telling us when it's time to sleep and time to wake up.

所以我们有个生物系统， 个时钟，告诉我们什么时候该睡觉和什么时候该醒来。

Satellite navigation systems ensure that the clocks on Wall Street all align, that commercial fishermen know where to go and, of course, that your Lyft driver knows where to pick you up.

卫星导航系统确保华尔街的时钟都对齐, 商业渔民知道去哪里, 当然, 你的 Lyft 司机也知道去哪里接你。

Get rid of a clock in a digital system, nothing makes sense anymore.

在数字系统中去掉时钟，切就都不再有意义了。
