I can see the argument for DST or no DST. I can even sort of see the argument for DST matching the economic powerhouse a few hundred miles away. But there is nothing in planetary physics to justify 3 different time zone usages in such a small area, with major cities being on a different one than all the area around them, or for one quadrant to be (mostly) different from the rest of it.
Moreover, there is only a 2 hour shift of sunrise/sunset from the peak of summer to the depths of winter. That's barely enough to justify the hassle of DST in my opinion.
