> Keeping accurate time is a modern thing. Before railroads, you could get along fine with just morning, noon, and night. Then the railroads came along and wanted to keep a schedule. They are largely responsible for time zones. I don't know who to blame for daylight savings time.

Even before railways, accurate timekeeping was a prized skill, and accurate clocks were fairly common. The main influence the railways had was to standardise the time that different towns kept, which began with books detailing the difference between "railway time" and the time kept at each town. Only when this got too complicated did towns actually start keeping to railway time.
