GA: How much time have my 100 most "obsessed" users spent on my site

Question

Does Google Analytics have enough information to answer the question of how much time have my top 100 users spent on my site? I don't need their user information, I don't care about ID or name which I know it doesn't even have. Just the identification of individual users by the cookie GA uses, and a report of how much time the top 100 loyal users spent on my site.

is such a thing possible at all with GA?

From your comment on Colwin's answer:

I don't need google if I have to track this for GA, I just hoped it already has this information such as "page visit duration" on a per-user, ongoing basis. If I had to feed Google that information myself, I can feed my own database and run analytics on it. Thanks anyway.

The Google analytics sessions is

a group of user interactions with your website that take place within a given time frame. For example a single session can contain multiple page views, events, social interactions, and ecommerce transactions.

Average session duration will be calculated as

total duration of all sessions / number of sessions
