> You could argue the same thing for pretty much all standards Of course, and you can argue colors of the sky and everything else. Back to the subject at hand concerning DST, its value is affected by presence of daylight, and that is different for different people. Not sure why you are bringing up a bunch of non-daylight related items into the discussion for comparison. Maybe some standardized law about requiring air conditioning or some law mandating sunglasses at certain hours on the clock would be more apropos. Regardless, comparisons here do nothing but deviate from the DST discussion. Obviously for some things commonality has value and for some things it doesn't, can't just say "let everyone choose everything then" as some form of counter or we cannot discuss productively.
