The main purpose of this legislation, known as the "Daylight Act," is to give states the option to observe daylight savings time year-round. This means that states could choose to keep their clocks set forward for the entire year, rather than changing them back to standard time in the fall. Key provisions of the Daylight Act include amendments to the Uniform Time Act of 1966. The changes allow states to decide by law whether to adopt daylight savings time for the whole year.
