https://en.wikipedia.org/w/index.php?title=User_talk:80.5.15.41&diff=479543777&oldid=479543767 This revision created a March 2012 section for a comment clearly marked 21:36, 29 February 2012. I suspect that this is something to do with it being the 29th of February, which only occurs in a leap year. (Once every 4 years. Except every one hundred years. Except every four hundred years.)
This might also be a timezone issue -- it looks like the user who made the edit is from Malaysia, which would be UTC+8 or so, making it March 1 in local time.
Doesn't affect latest dev version
