I've stopped keeping track of all the proposed US legislation to end daylight saving time. Bills have been introduced or passed in states ranging from Alaska <https://www.abc27.com/news/local/state-lawmaker-proposes-to-eliminate-daylig...> to Wyoming <https://www.wyodaily.com/story/2019/02/14/news/daylight-saving-time-bill-die...>. None of the bills that have become law have changed civil timekeeping in any way, and I suspect that this is by design. Most Americans want to stop fiddling with the clocks twice a year. Some want to move one timezone east (so-called "permanent DST"), while others want to stay on permanent standard time. Although the former typically outnumber the latter, any change will be controversial and state legislators prefer doing nothing to dealing with the blowback that would come from any real change. I suspect this is why many legislators seem to be happy to do what the Washington House has done, which is to pass a bill that doesn't really do anything, and blame the problem on Washington.
