Would it be difficult to use phrases like "as of 2007" more often?
You may be interested in [[Wikipedia:As of]] and associated talk page. Unfortunately, it is not marked as "guideline" or "policy", so I have no idea if these pages are at all sensible. (also 1/2 :-)
I was thinking something along the lines of a template saying "this article contains facts that may not be true in the future", but any thoughts?
See [[Wikipedia:Updating information]] and {{Update after}}.
(Note: I don't know if these pages answer all your questions, and if use of this template is accepted. Just pointing at some relevant and perhaps useful information)
