The "lighter later" campaign is cretinous. I like getting up with the sun. Getting up and going to work in the dark is depressing as hell. On the flip side, I expect it to be dark in the winter in evenings. You want to go outside in the evenings in winter? Why? It's fucking cold and wet and it will be dark pretty early even with GMT+1 time. You want to do sport in the winter evenings? Do it indoors.
In summer, the days are so much longer it doesn't make much difference whether we're on GMT or GMT+1, so my vote would actually be for sticking with GMT all year round. Where's the "lighter when I wake up" campaign?
