The UK operates on GMT, Nigel. Not picked enough nits yet?

Sigh.

No, the UK operates on GMT for the present, but that is for the smaller part of the year. For approximately 7 months out of 12 it works on BST (British Summer Time)

I'll see your 'sigh' and raise you one.
Anyway, my comment was on what time zone(s) the EU works on.
