Expired (but brand new) Access tokens

I guess I more leaving this here in case anyone else runs into this problem.

I can't lay my finger on exactly what is causing the problem I'm having, but here is what happens.

From the command line I have the whole thing working just fine, I re-implemented everything as a web call from PHP and the access tokens are expired as soon as I make a call for them.

I'm not sure if I missed part of the set up, or something else, but my solution was to

1. Edit the database and set expires in the oauth.oauth_access_tokens table to a varchar (20) (anything over 10 should work).
2. Edit Pdo.php and comment out the "$expires = date('Y-m-d H:i:s', $expires);" lines, and comment out the line "$token['expires'] = strtotime($token['expires']);".

This removes all the unnecessary (from what I saw, but maybe I missed something) time stamp to time string conversions, and solves my problem.

Hope this helps anyone else that had this issue.
