I'm slightly surprised that no-one has suggested adopting the Indian
solution (UTC+4h30m), which is ideal for political areas that are
about 30 degrees east to west, and switching the EU to UTC+30m (plus,
or not, daylight saving in both cases). I suspect that if you take
each EU country and multiply its population by the error between solar
and civil time, and then minimise that function, you'd end up
somewhere around that value. Portugal has tried CET, but is currently
back on WET, and the UK is muttering about CET: in both cases, UTC+30m
would be a good compromise between solar time and consistency. It
would be a problem wrt the US, but India copes, and conversely it
would make it easier with respect to India.

We could drift there by applying 1800 leap seconds, one a night for
five years :-)
