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

夏令时，简 DST，种提前时钟的。

To counteract this, physicists engineered a double-clock system, with two sets of ytterbium atoms being sampled by the same laser.

为了抵消这点，物理学家设计了个双时钟，用同激光对两组镱原子进行采样。

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，我们有个计算来分析整个时钟集合，时间间隔大约 100 秒。

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 司也知道去哪里接你。
