GMT and putting the clocks back

Now that we have arrived at my favourite day of the year, when the clocks go back and we can all have an extra hour of slumber, there is the predictable and tiresome chorus of nincompoops who want us to stay on British Summer Time all the year round. It is bad enough having to endure this abomination for six months, never mind about all year round. I say let us stay on the time zone we were clearly meant to be on, viz good old GMT, all year round. I know there are the silly arguments from the Eurofanatics that it will put us on the same time zone as the rest of Europe, but does this matter in the slightest. I don't believe any less business is going to be transacted in six hours than in eight, and if people are that obsessed with the number of co-ordinate hours of transaction time we might just as well put the clocks back by eight hours to be on the same time zone as California.
I remember the experiment with this back in the early seventies when it was sensibly abandoned because it meant those in Scotland were getting up in pitch darkness. Whatever time zone you are on there is difficulty but we might just as well stick with the natural one.
