"The wall clock should remain constant, and our routines should change. That would be more logical than trying to falsely adjust a 'constant'."
Do you mean the 'constant' time at which the sun sets?
If BST were abolished, I'm pretty sure my employer would agree to me working 08:00 to 16:30 in the summer. Would yours though? Would everybody else's?
I'm sticking to my guns --- and probably inviting repeats of my earlier downvotes --- I would rather have more daylight hours after work than before work. My ideal job is probably refuse collection: start early, several hours of physical labour, be out of work in time to collect the kids (now sadly grown up) from school.
Yes, almost everything can be done by artificial light, farming, commuting, working --- but some things are nicer in long evening daylight: sitting in the garden; walking in the countryside; messing around with horses, boats, model aircraft, etc. I do realise that some people would rather have daylight for a morning run than an evening one, but it's always going to be like that ...
... unless ... we have alternate months of BST and GMT during the summer. Any takers?
