Hollydolly and her Brits did this a week ago. It's time to change the frikken clocks. There is no real scientific data that this does anything but irritate people. The best data says MAYBE there's a third of 1 percent savings, but that depends on location. Now, for the next week, I'll feel lousy, miserable, out of sorts. It's like calling Monday, "Sunday", so you'll have three days off, but you still have to go to work on the second "Sunday".
There are bills in the US & UK to abolish DST, with overwhelming approval, but haven't enacted them. Australia has repealed it, and OZ hasn't yet fallen into the sea.
I hate this changing time thing.
