I do remember when we had no daylight savings time in the US. Each state, or locality had decided to no longer do such officially so daylight savings was gone except in two or three states. So, to make things equal all over once again, our nations Congress decided to END daylight savings time for everyone officially. No that would be making sense, something our national Congress just does not do at all times. So instead of ending daylight savings time they push daylight savings time back on for all states mandatory rather than taking daylight savings time away and offered all states the right to end daylight savings time if they chose. IF THEY CHOSE? They had already taken that step but our Congress refused that choice. Well, I think a couple or three have once again taken that choice.
What was done where I lived was for the businesses in my town in northern Ohio just south of lake Erie, was to locally allow their people to come to work at different times by local elections. Where I worked had two start times for a few months in May to September. You had to choose for your self which way to go and stick with it for the selected months. Shifts in shift work areas had to agree or not. In my drafting job it was up to each individual as there would not be any conflict. That optional system seemed to work and most folks as I remember it did object when our not so smart Congress of those days brought daylight savings back into business.
But in one state, where I now live, did toss DST and went back onto national time as waiting for heat to really get started prior to start work made no sense at all. I watch as our outdoor work assignments have their hours start earlier in the summer, rather than later. That way they do get to take off as the late afternoon heat takes over.
If folks prefer to sleep in till it is light out, or to get up before it is light out, should do so on their own and not demand that the entire country must do so. Fact is that for the US the time difference is greater in the northern states than in the southern states. So for me it should be time on a national basis all year around. No more trying to outsmart mother nature with meddling with the clocks. Not all folks in the US ever really like DST at all and most states had individually decided to not adapt to daylight savings time and let their people choose to live the way thay wanted without clock fiddllng.
