Today we spring forward and as a happy night-owl I agree with Robertson Davies (emphasis added):
“I don’t really care how time is reckoned so long as there is some agreement about it, but I object to being told that I am saving daylight when my reason tells me that I am doing nothing of the kind. I even object to the implication that I am wasting something valuable if I stay in bed after the sun has risen. As an admirer of moonlight I resent the bossy insistence of those who want to reduce my time for enjoying it. At the back of the Daylight Saving scheme I detect the bony, blue-fingered hand of Puritanism, eager to push people into bed earlier, and get them up earlier, to make them healthy, wealthy and wise in spite of themselves.” (Robertson Davies, The Diary of Samuel Marchbanks, 1947, XIX, Sunday.)
I suppose it’s useful, but I have my doubts. For all the upheaval, there doesn’t seem to be any significant returns. Given the choice I wouldn’t rearrange my life for measly returns of one (or less) percent and I doubt most would, but that’s DST in a nutshell.
