Be sure to set your clock back or you’ll be an hour early for class!
“Daylight Saving Time is a change in the standard time of each time zone. Time zones were first used by the railroads in 1883 to standardize their schedules. Trains had made obsolete the old system where major cities and regions set clocks according to local astronomical conditions. Canada’s Sir Sanford Fleming advocated the adoption of a standard or mean time and hourly variations from that according to established time zones.
In 1918, the U.S. Congress made the U.S. rail zones official under federal law and gave the responsibility to make any changes to the Interstate Commerce Commission, the only federal transportation regulatory agency at the time. When Congress created the Department of Transportation in 1966, it transferred the responsibility for the time laws to the new department.
The American law by which we turn our clock forward in the spring and back in the fall is known as the Uniform Time Act of 1966. The law does not require that anyone observe Daylight Saving Time; all the law says is that if we are going to observe Daylight Saving Time, it must be done uniformly.”
