Early to bed Early to rise
Makes a man healthy, wealthy and wise. Alternately eat worms it depends on your point of view.
Of course daylight saving is essential.
I really did not have to deliberate as I am naturally up about an hour before dawn, so when I turn functional it is daybreak I can do away with the lights or whatever.
Turning in an hour early is of course useful.
But one is an biological owl then i think a compromise should be worked.
