It says "Jan 11".
Is that Jan 11th of this year? Or January of 2011? I have been on Stack Overflow since 2008 and I have no idea when Seasoned Advice started, so it's not far-fetched that I asked a question in 2011.
It's too ambiguous. Add an ordinal suffix to make Jan 11 into Jan 11th. Or add the year: Jan 11 2020. Or use European style: 11 Jan 2020.
Or just use the same style for every date: "answered Oct 15 '18" like this answer in the same thread. I would only know that Jan 11 means "this year" by looking at other answers from different years (if there are any).
