I would like to report a bug. This post was apparently closed 2 years ago, but it has only existed for 1 year and 3 months. See a screenshot of the problem below.
This will be fixed in the next build.
I'm just doing a minimal fix here so that things closed more than 1 year ago and less than 2 years ago are considered "1 year ago" instead of 2.
Both the Asked date and the Closed date at the top of the page use their own bespoke date formatters that are different from the standard one used on things like comments. Each has specific strengths, weaknesses, and quirks, and merging the two is a much more complex discussion.
