Date abbreviation for 2020 shown as `'0`
The main page summary for posts, and the "info box" that accompanies each post, includes a date abbreviation like:
Dec 25 '19
But for posts in 2020, the abbreviation looks like:
Apr 22 '0.
Clearly that's a bug — it should read:
Apr 22 '20 using the last two digits of the year.
Hopefully an easy one to fix!
@Evgeny -- This bug can be observed on Ask Askbot here, and also on Ask Sage. Could not see an issue or a pull request for it in [the askbot-devel issue tracker](https://github.com/ASKBOT/askbot-devel/issues?q=sort%3Aupdated-desc) but it would be nice to fix.
