I just released a module called Net::Gnip to CPAN and it accidentally contained an inner package called DateTime::Format::XML which parses
http://www.w3.org/TR/xmlschema-2/#dateTime style dates using DateTime::Format::8601 and formats them using a strftime. Unfortunately PAUSE appears to have extracted the package and so I've polluted the DateTime namespace. I'm going to do another release which fixes the problem and then delete the old package. Apologies. Simon
