I asked a question yesterday on SO and after many edits of the question and of the two answers we got to the point where I was able to confirm that both answers were correct. As I can only accept one (I'll at least up vote both), I'm trying to figure out which of the answers was correct first so I can accept that one. I tried the "oldest" tab on the answers, but wasn't sure if that sorts by original post time or last edit (if any) time.
How can I (a user with 2700-odd rep) figure out when each of those answers were finally edited with the right answer? Failing that, I'll take suggestions on how best to break the tie between the two answers.
p.s. the two answerers have to recuse themselves here :)
