100 Years of Standard Time

Have you ever wondered how the United States was divided into time zones?  Curious about the reason we "fall back" and "spring forward" every year?  We were too!  Turns out this year is the 100th anniversary of the Standard Time Act of 1918.  Also known as the Calder Act, the Standard Time Act of 1918 was the first federal law in the U.S. to establish Standard time and establish Daylight saving time.  More importantly, it allowed the Interstate Commerce Commission to define our time zones.
