...quite how bad the effect of changing the clocks from BST to GMT is. As I compose this (as opposed to go online and publish) it's about 16:45, and the sky is dull grey, a little off-apricot in the southwest where the remains of sunset are. It's getting dark and not yet going home from work time. Certainly it's time to need artificial lighting to do anything detailed except close to a window. Ugh!!
