> GB should switch to UTC+0 all year. UTC+1 all year was tried (1968-1971) and was very unpopular in Scotland. School hours are roughly 09:00 till 15:00 and they only get about 6 hours of sunlight in winter up north so local noon has to be at around 12:00.
Couldn't you adjust the school schedule by an hour to achieve the same effect?
You mean switch to UTC+1 all year while doing +1 on the timetables of all schools and anything else that might directly or indirectly depend on them: childcare for younger children, working hours of teachers and parents, sports activities, public transport, ...? Compared to switching to UTC+0 all year and leaving the timetables as they are, the disadvantages would seem to greatly outweigh the advantages.
The other confusing thing about this discussion is that when you include timetable changes there are quite a lot of options and it's not always obvious which alternative people are comparing an option against. To be honest, the current system with clock changes isn't the worst possible option. Perhaps it's the second best.
