Has it seriously not occurred to you that you're not actually making the sun set any later, you've just changed what the clock says when the sun sets in its own good time? And that the time is changed just as much at sunrise? 🙄
I saw a quote on FB the other day - something to the effect that "only the government could think that by cutting a foot off one end of a blanket and sewing it onto the other end, that you end up with a longer blanket."
