Well, British Summer Time anyway. We first moved away from Greenwich Mean Time in 1916 as a wartime measure, but adopted it as part of normal life in 1925. And it was one William Willett who came up with the idea. Idiot – what’s wrong with sticking with GMT? You don’t get more daylight. Get up earlier if you want more daylight in your life.
Anyway there is a dial in Pett’s Wood, in SE London, which is marked with summertime hours, that commemorates this man. I know this because its in a book called ‘The Wayfarer’s Book’ by E Mansell. Published by Ward lock in hardback, price 3/6d. No year of publication.
