@Ga boyFYI, Spurs play at home this Sunday at 9am Eastern. The game is on USA.
London is 5 hours ahead so that would be the equivalent of a 2pm start. Obviously London is significantly further North than Buffalo so that plays into the sun angle also, but you'll get an idea of what the sun will do in general. London is roughly the same latitude as Saskatoon and is almost 10 degrees further north than Buffalo is. For scale, Buffalo is 10 degrees north of places like Dallas and San Diego.
