Here's a Q&A that Matt Cutts published in October 2010. The specific question asked was "how does Google determine domain age". In it Matt talks about the fact that Google uses a variety of means to determine domain (and page) age such as when Google first saw a link to a domain or page or when domain or page was first crawled.

I think the point he's making is that Google doesn't rely on a single variable when making ranking decisions. A change to the DC.date.created will likely be noted, but the fact that your site was previously found and indexed will carry more weight.

I don't know that definitely. I did do a search on Bill Slawski's site (seobythesea.com) to see if he an opinion that was patent-based but didn't find anything.

In my experience, the date created referred to the page itself as opposed to the entire site. I have migrated about 20 sites and this has not created an issue at all. As long as your domain doesn't change you should be ok. Part of the domain age is when it was first registered, how long it is registered for and whether or not it is an active site. New pages get added to sites all the time. The "date created" is another tag for Google to be able to use to know that there has been an update and there is new content to crawl.
