Do my biological rhythms know when is the middle of solar day? Or maaaaybe the stable day regime?
In my whereabouts sun raises at 3am around midsummer (it would be 2am without DST) and at 9am around christmas. Nowdays I wake up at 7am around the year and somehow my biological rythm is fine. It used to be just fine when I waking up at 10am too. The core thing seems to be stable day rythm, not adhering to solar time.
What you're saying is sunrise matters, not solar time. Although even for sunrise, I'd say students' daily routine matters much more. Back in high school, when I spending my late evenings and nights on computer, I didn't care if it is bright or dark in the morning, i was sleepy anyway...
I'd also argue that in today's sedentary world luring people outside is very important. And bright spring/summar/fall evenings is very important at that. There's plenty of evidence for the benefits of exercise, socialising and so on. And with forever-non-DST time, we would loose that for couple weeks improvement in the morning.
