Tick, tock

Changing the clocks time - a job I thoroughly dislike.  But as ever when we put the clocks forward, there are calls for us to stay on summer time for the whole year. Then, the argument goes. we would be on the same time as France, Germany and the rest of Europe, which would make trading with them much simpler. Except of course that it wouldn't - those on Central European Time also put their clocks forward in the Spring, so we would still be an hour behind them!
