Having lived for a good chunk of my adult life in countries that don't put the clocks forward or back, I have realised it is completely pointless and Mr H is entirely correct
'Two types are keenest on fiddling with the clocks. The first type are despots, who are at least know how unpleasant they are. The second are urban bourgeois bohemians (BoBos) , who rise late and go to bed late, and only experience dawn if they have been at a particularly good party, and are surprised by sunrise on their bleary way home.' https://t.co/FNBQCBCZ2A
