People ask about the latin tag in my signature file. It means loosely 'I only count the sunny hours'. I grew up in a suburb of London called Petts Wood which is near Bromley where  I was born. ItThe wood  originally belonged to a family of ship builders who used the wood for raw materials. One of  Petts Wood's claims to fame is that it was the home of one William Willett who was the promoter of  Summer Time. When the housing part of Petts Wood was built in 1929 part of the wood was preserved and in the wood is a memorial to Willett which has on it a sundial with this line on it. I used to play in the wood a lot when I was a child.
