Mean old time - Telegraph Janys and John Warren of Weston-super-Mare say they save a third from energy bills by refusing to change to Greenwich Mean Time, as we all shall on Sunday. It seems to them that they get more light. This is an illusion: daylight remains the same. But by sticking to their summer bedtime of 11pm (10pm for us Greenwich Mean-minded clock-watchers), the Warrens find oblivion for an extra hour each night. Their secret is to get up at 9am GMT (10am by their summery timepieces). This is cheating. Anyone can stay in bed for 11 hours if they try. It shows no gain from BST, which is an annual confidence trick to lure us from bed early. GMT is real time, in Greenwich. By Weston-super-Mare's natural time, everyone should get up 11 minutes 54 seconds later. Since 1840, they have given up that lie-in for the sake of society - and catching trains. We can't all work on Warren time.
