On this day in 1883, American and Canadian railroads instituted standard time zones (Eastern, Central, Mountain, and Pacific). Prior to this standardization, each town set its own time by when the sun appeared highest in the sky. This resulted in a wide variety of times from place to place. With a rise in train travel, it was understandably challenging to write schedules, hence the creation of standard time zones.
The U.S. government didn’t adopt the system until 1918 with the Standard Time Act, which also established Daylight Savings Time.
Did you know? A difference in time could result in life-or-death situations on the railroad. Time discrepancies could (and did) result in collisions from trains being on the same track at the same time.
