DST in the USA Today
According to section 110 of the act, the US Department of Transportation (DOT) governs the use of DST. The law does not affect the rights of the states and territories that choose not to observe DST.
Confusing DST Rules
Historically, there were no uniform rules for DST from 1945 to 1966. This caused widespread confusion, especially in transport and broadcasting. The Uniform Time Act of 1966 aligned the switch dates across the USA for the first time.
After the energy crisis was over in 1976, the DST schedule in the US was revised several times. From 1987 to 2006, the country observed DST for about 7 months each year.
