> I live in a small country where a lot of our businesses work with neighbouring countries. There is even a significant percentage of people that live here but go to work to another country. So, the kids' kindergarten will use a different time than your workplace?
I think that's a fairly small problem, and there's a good chance that it'll solve as many cases as it makes worse. For example, the longest single border within the EU is Portugal/Spain. Right now they're in different timezones, but that doesn't make a lot of sense - it leaves Spain in the same TZ as Poland, and with a noticeable unusually late sunrise/sunset. This would be a nice chance for Spain to sync up with Portugal/the UK/Morocco instead, all of whom match its longitude much closer.
Might well not happen, but it's certainly not clear that it'd make life more difficult than it is now.
