Virtually all of this region is west of the theoretical western border of the zone at 67.5°W; only a small portion of Maine lies east of that meridian. A Massachusetts commission concluded in 2017 that the benefits of changing to Atlantic Standard Time year-round would outweigh the disadvantages, provided that a majority of northeastern states make the same change. In May 2017, the Maine Senate approved a change to AST, on the condition that there would be a referendum, and that Massachusetts and New Hampshire decided to make the same switch. Also in 2017, the New Hampshire House of Representatives approved a bill in favor of a regional change, but this was voted down by the state's Senate. Similar bills have been put forward in Connecticut, Rhode Island, and Vermont. In 2018, Florida enacted into law the "Sunshine Protection Act", under which the state would observe daylight saving time year-round. Most of the state would permanently keep Eastern Daylight Time, which is equivalent to Atlantic Standard Time; the state's panhandle region would move to year-round Central Daylight Time / Eastern Standard Time. However, the change cannot take effect until it is passed into federal law by the United States Congress. On March 15, 2022, the United States Senate voted unanimously to advance a federal version of the "Sunshine Protection" legislation from Florida, also called the "Sunshine Protection Act", to the United States House of Representatives. If the bill passes the House and earns the president's signature, Daylight Saving will be made permanent in most of the United States in November 2023, effectively making the parts of the US in the Eastern Time Zone a part of the Atlantic Standard Time Zone year-round.
