Today in History: Daylight Savings Time

On this day (March 19) in 1918, the U.S. Congress established time zones across the United States and began the practicing of adjusting the clocks for Daylight Savings Time. The idea was first proposed by George Hudson in 1895 as a way of maximizing sunlight in the evenings so that industrial workers would be able to enjoy daylight at the end of their workdays.
