Replaced date-functions by their utc-quivalent in the XML-RPC library.

Ignore-this: e74f051d409c2df9e59f6f0b42f362f8
According to the specification of the wiki XML-RPC api at
http://www.jspwiki.org/wiki/WikiRPCInterface2 all returned datetimes
should be UTC. This commit changes the date-functions in IXR_Date to
make DokuWiki obey to this specification (otherwise there is now way
to get from these datetimes back to a timestamp for example).
