I don't want children to have to travel to or from school in the dark. It's dangerous by bicycle (a lot of children cycle), and unpleasant in any case. If you're at a reasonably high latitude that means you need the middle of the school day to be around local noon in the winter. Round here, in the UK, school days typically run from a bit before 09:00 to a bit after 15:00. So something close to astronomical local time would be a good choice of time zone. You could move the time zone three hours and at the same time change school hours by three hours, but what would be the point of that? School hours is the main thing that isn't flexible. Office hours vary. Shops can easily be flexible. There's the stock exchange, I suppose, but most people don't interact with that. So the obvious thing to do is to abolish summer time and leave winter time as it is.
