On Tuesday, the US Senate lodged a rare unanimous vote on a bill that could have drastic technological and transportation implications: a permanent, year-round adherence to daylight saving time (DST).

The one-page "Sunshine Protection Act," as co-sponsored by Sens. Marc Rubio (R-Fla.) and Sheldon Whitehouse (D-R.I.), is now cleared for a vote in the House of Representatives after passing by unanimous consent in the Senate. This bill, as originally filed in 2018 and reintroduced in 2021, would reverse the Calder Act's introduction of a twice-a-year clock-change process in 1918, along with its eventual reinforcement by the Uniform Time Act of 1966.
