It's a partial solution in that I don't know how many people would start accepting 1 day games? As it is, of course, someone who wants to make games last for months can get all the games they want, regardless of how their opponent feels about it. All some (maybe many, maybe even most) of us want is a way to determine like-minded players when it comes to expediency!! If you don't need this, fine, ignore it!

p.s. I even tried going to players' games and clicking on their moves hoping to see the time between moves, no such luck.
