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.

每个钟的所有信息都在这里，我们有一个计算机系统来分析整个钟，间间隔大约是 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.
