If I get more than one correct answer, I want to accept the earlier one. When both answers are posted at the same hour, the site displays something like "answered 2 hours ago." I have no way to determine which answer came first.
I also don't know the cut off of when the number of minutes shows up. It seems I have to wait for maybe a day.
So, instead of "answered 2 hours ago," I suggest we display "answered 2 hours x minutes" ago.
