I've gotten a few Necromancer badges for answering questions that were months or even a couple of years old. In some cases, the OP came back around to grant my answer as the accepted solution.
It got me wondering this:
What's the longest length in time from when an OP posted a question to when the first accepted answer was entered?
Don't count the time for when the OP came back to accept. Don't count answers to questions that already had an accepted answer.
