Quizplus · Accepted Answer

The railroads established the first time zones in the United States in 1883 to standardize schedules and avoid confusion caused by different local times in different parts of the country. While Congress did ultimately pass legislation endorsing the time zones, it was the railroads that first implemented them. The President and the army did not play a significant role in establishing the time zones.
