I'm talking about how it passed, not the contents of the bill.

However there are arguments for both sides, even using your arguments above.

Playing devils advocate, the most extreme times have our most northern cities having sunrise at 7:30am vs 8:30am and sunset at 4:30am vs 5:30am.

Most people work 7-3 or 9-5 (and if they don't it's dark either way). Anyone working a 7-3 leaves too early and gets out too early for a change to matter. It's going to be dark regardless. However people working 9-5 are leaving while it's still a little light out with DLST, but driving home in the dark. Overall there's less dark commuting with DLST.

As for school children, they should be going to school an hour or two later regardless. Assuming a half hour commute, only 17% to 57% (likely much closer to 17%, but I don't have the full data) of schools would be beifited from standard time anyway.

Then there's the economic impacts. People are more likely to shop when the sun's out, so the later the sun is out the better for business.

Either way we really need to just pick one.
