Knowledge Search result shows inconsistent dates on $knowledge.do and kb_find.do pages

Knowledge Search result shows inconsistent dates on $knowledge.do and kb_find.do pages.
e.g. kb_find page shows this article was updated 8 months ago, but $knowledge.do page shows differently.

1. Suppose an article has updated on 13th August, 2019 (Take article KB0000001 from Demo Data).
2. And let us suppose, today's date is 2nd May or 25th April, 2020. Search for this article in kb_find.do and $knowledge.do.
3. We can see that kb_find shows this article was updated 8 months ago, which is right. However, $knowledge.do shows, this article was updated 9 month ago, which is wrong. Technically, it should show, was updated 8 months ago.
4.However, if we set today's date to 20th april, $knowledge.do shows, it was updated 8 months ago, which is right.
