1883 - A standard time zone was established across the whole of America

At exactly noon, the United States and Canada readjust their clocks and watches to reflect four continental time zones, and end the confusion of dealing with thousands of local times. With no agreed time zone previously, different villages across America set their own local times based generally on ‘high noon’, the time when the Sun was at its highest point in the sky. This, however, became an increased problem with advancement of the railroad system, as all stations listed their own time zones causing a scheduling nightmare. So the railroad companies took it upon themselves to create a new time code system across the country.
