There was NEVER any need to change any clocks. All the adjustment needed was, if anyone wanted, is and was to change schedules, not the clocks.
You think on March 9 you should get up at 9 am instead of 8 am, fine, do it, and as many as want to do the same, in your town, city, business, county, state, industry, that’s fine. But no one ever NEEDED to change the clocks.
Other way around if you want to emulate DST. Get up at 7 AM instead of 8AM.
