Sen. Marco Rubio announced Wednesday that he's filed legislation to allow not just Florida but the entire nation to save daylight all year round.
Rubio took this initiative a week after Florida's Legislature voted to make their state the nation's first to adopt year-round daylight saving time statewide — a change that can't take effect unless Congress changes federal law.
The first bill would make daylight saving time permanent across the country.
Nationwide daylight saving time began 100 years ago during World War I.
After each war, Congress rescinded the national laws but many people liked the extra hour of sunshine at the end of summer days, so some states and even cities observed daylight time while others kept standard time year-round.
