Here in the UK, as almost everywhere else in Europe, we went back to winter time last weekend: Sun 27 Oct 2013.
The UK and the Republic of Ireland are on GMT - so are one hour behind most of Europe which is on CET (Central European Time). CET includes Spain, Germany, Italy, France, BENELUX, Poland, most of Scandanavia and several other central European countries. This makes CET among the most populous time zones in the world with around 350 million with their watches on this time zone.
Periodically, there's a debate at government level as to whether the UK should adopt CET. This was last discussed in 2011.
http://www.bbc.co.uk/news/uk-politics-15490249If the UK adopted CET, we'd be in sync with most of the rest of Europe. But it would increase the time difference between the UK and the US East Coast from 5 to 6 hours for most of the year.
Personally, I like the idea of UK moving from GMT to CET. In June and July, it wouldn't dark until 23:00, and we'd be spared the annoying hour's change whenever we cross the English Channel. But there would a price to pay. During the shortest days, it would not get properly light until 09:30. And it would be worse in Scotland, being further north - full day light would not come until 10:00 in the morning for some weeks.
