Sir: Dora Thomas (letter, 4 November) is wrong in saying the experiment in all-year-round British Summer Time only lasted two years. Between October 1968 and October 1971 clocks were kept one hour ahead of Greenwich Mean Time throughout the year. This was known as British Standard Time. I personally loved the lighter evenings and thought the darker mornings a price well worth paying. It really is a question of personal preference and individual circumstances.
My memory goes back further to the Second World War, when we had "permanent" summer time and from May to August Double Summer Time, with the clocks two hours ahead of GMT.
The long light evenings were wonderful, although all this was, of course, done to make it safer for workers going to and from work.
