Yes, but that's the very idea behind daylight savings time too - it's easier to change the clock than to establish a norm that every organization opens and closes an hour earlier during the summer (or rather, the easiest way of establishing that norm is changing the clock). "Permanent DST," for similar reasons, is easier than having everyone do a one-time change of their schedules.
