How Did the Idea of Time Zones Begin?

Imagine everyone in the world uses the same clock, it would be chaos! Before time zones, people all used the time from their local sun, so someone in France might eat lunch at 1 o’clock while someone in Germany eats it at 2 o’clock. That didn’t work very well when trains started running fast across countries. In 1847, a man named Sir Sandford Fleming had an idea: divide the world into chunks where everyone shares the same time, and that’s how time zones began.
