Okay, but some schedules are inflexible in practice, and "just change the time you do things" is also an argument against DST.
Oh, it definitely is. Though, DST has a bit more of a bite, since people won't just adapt to it by moving things over one by one. (Because it goes back to sane for half a year every year.)
In Spain, there are in `the wrong' timezone, ie they are on German/Polish time. As a result, life still happens at reasonable solar times, but at late wallclock times.
