Sort fans of a facebook page by join date

I can't seem to find a way to find out the chronological order specific users 'liked' a page. The m开发者_开发百科ain purpose would be to award lets say the 5000th user that joined "my" page. However, as much data as possible is also beneficial - be it acquired via standard means (via facebook site), or the facebook API (which I currently know nothing about).

P.S. I hope I'm asking this on the right page, if it should be moved to one of the stack exchange sites, let me know or just do so.

There's no API solution for this, and the fan list isn't ordered chronologically on the site. This is by design.
