It seems ask.sagemath.org (or rather Askbot) has fallen prey to the Y2k20 bug, just in its date format. Just look at how the dates of some posts or comments are formatted: Previously they would be displayed like "Dec 31 '19" and now they display "Jan 7 '0" with the year formatted as "'0" instead of "'20".
I don't know if it's worth doing anything about; I just found it amusing.
