Is there evidence of <meta name="date" content="..."> being part of
Google's freshness factor? Is there public documentation explaining what
<meta name="date" content="..."> means, what date format expected in the
content attribute is and what software does something useful with it?

No, it's not.

It simply hasn't been registered yet. Is there any evidence of consuming
software that does something useful with dc:created?
