Was it that long ago? I don't follow these things closely, but the infamous talk where he repeatedly propositioned a female audience member was in 2010, I believe, and it seems so far removed from his current rhetoric (although he still refuses to admit that it was in any way problematic) that his change of heart taking place immediately afterwards would seem a little incongruous to me.
You're right, it's probably not that long. Elevatorgate was in 2011 and I think that's roughly when PZ switched to the new war.
