time zone（n.）
1885年，源自 time（n.）和 zone（n.）。与英国和法国一样，全国统一时间的运动来自铁路。
Previous to 1883 the methods of measuring time in the United States were so varied and so numerous as to be ludicrous. There were 50 different standards used in the United States, and on one road between New York and Boston, whose actual difference is 12 minutes, there were three distinct standards of time. Even small towns had two different standards one known as "town" or local time and the other "railroad" time.
... At noon on November 18, 1883, there was a general resetting of watches and clocks all over the United States and Canada, and the four great time zones, one hour apart, into which the country was divided came into being. So smoothly did the plan work that the general readjustment was accomplished without great difficulty and it has worked satisfactorily ever since. [Railroad Trainman, September 1909]
在1883年之前，美国测量时间的方法如此多样化和繁琐，以至于令人发笑。在美国有50种不同的标准，而在纽约和波士顿之间的一条路上，实际差异为12分钟，却有三种不同的时间标准。即使是小城镇也有两种不同的标准，一种被称为“城镇”或当地时间，另一种是“铁路”时间。
... 在1883年11月18日中午，美国和加拿大各地的手表和时钟都进行了普遍的重新设置，国家被划分为四个相隔一小时的时区。计划执行得非常顺利，普遍调整没有遇到太大的困难，自那以后一直运作良好。[铁路工人，1909年9月]
