Bung the clocks half hour between the two and keep it there all year round ?
Aha, a compromise.
@User is right about making the case for change. But I'm in the camp that doesn't actually want a change. I don't want a change of clock time, that is. But, apart from agriculture and schools (from the point of view of safety) how many people are doing time- or daylight-sensitive work? I suspect that the daylight-sensitive work is far less important with improvements in lighting. Besides, the agricultural side is already pretty much in tune with the seasons, with their variable sunrises and sunsets, not the time on the clock. They already make the adjustments with little reference to the clock. And, again, better lights extend their working window.
Time-sensitive work is nearly always a matter of coordination with others or, in the retail sector, when there's a large enough mass of people prepared to part with their money. So, for the retail sector, open when people are about. People who need to coordinate with people in other completely different time zones already work non-standard hours. The hours they work are already adjusted to those distant time zoners.
The only way to get rid of dark winter mornings is to get up later or move south. The only way to get longer summer evenings is to do get up early and do everything earlier.
The problem of schools is primarily safety. Road safety. Tired people rushing home in the dark after long days aren't as likely to spot children as people not tired and hungry and rushing home would be. But that's another tyranny. I suspect many cyclists and A&E departments will be aware of the drop in driving standards in the late afternoon. Adjust the school hours to the best time for the children's wellbeing and safety.
Who really needs a clock change? It's a kind of flexibility but it's completely regimented and compulsory when it doesn't need to be. The real flexibility will get built in without the clock changing biennial ritual.
