Ah but Gibraltar isn't part of the United Kingdom! In fact the only territories that are are Scotland, England, Wales and Northern Ireland. Not even the channel islands or Isle of Man are officially part of the UK.

It would be more useful I think if the whole world just agreed it was going to scrap daylight savings time completely and keep the clocks the same year round. Although admittedly clock change time is the only time I reset my clocks at home; some of which can be up to 10 minutes out by the time the 6 months has elapsed!
