Map

For as long as I can remember, there has been a map in the ticket hall of Piccadilly Circus tube station supposedly showing night and day across the time zones of the world. | But this map has always fascinated me, and still does, even though it now seems very primitive. | This is somewhat surprising given the London Underground's historic difficulty in grasping the concept of punctuality. | This is because it chops the world up equally by longitude, without regard to the reality of either political divisions or the changing seasons.
