DokuWikis XML-RPC Backend gives a date format that is invalid according the XML-RPC spec.
According to my mailinglist post
http://www.freelists.org/post/dokuwiki/XMLRPC-Date-type-format here is the bug.
When you get a response from DokuWiki XML-RPC within a date (like getAllPages) the format is yyyy-mm-ddThh:mm but according to the spec it should be yyyymmddThh:mm.
