I still don't get it. During the winter, the daylight hour is literally shorter, not just shifted. Shifting one hour won't magically make it longer. At best it gives your more daylight in one end, while sacrificing the other (and more than 1 hour, since again, the total daylight hour is shorter). So why bother?

Because the idea is that sunlight during a particular part of the day is more valuable. One reason I've seen given (not saying I agree with it) is that if you "move" the sunlight to the morning, it means kids won't have to wait for the school bus in the dark. Or if you "move" it to the afternoon, then there will be a little bit of daylight at the end of the day for people working 9-5, which might be useful if you want to go for a run or something.
