On this day in 1883, time zones launched in the United States. Prior to the time every major city had a “noon stick” where the sun being overhead set the time for noon and time was extrapolated from there. Who cared if Boston was a few minutes earlier than New York when the two were days apart on horseback.
The railroads changed all that. And industry came together–albeit with heavy hand by the Vanderbilts–to solve the problem.
Think a problem today is too big for industry standards to solve? Check your watch.
