  Isn't t actually referring to a timezone (theoretically
  located anywhere) that is presently operating one hour
  *AHEAD* of UTC? It could be the next timezone east of
  Greenwhich when they are operating on their winter time
  hours or it could be Greenwhich itself when they are
  Operating on Summer time.

I believe you are mistaken.
This is not UTC.  The "+0100" refers to the first timezone to the east of Greenwich - Central European Time, I believe.

You may find this document useful: <http://www.w3.org/TR/NOTE-datetime.html>
and this reference: <http://en.wikipedia.org/wiki/ISO_8601>

You may also want to check out the QDateTime::fromString methods as the string you show is not in a standard format (like ISO 8601), but it can be parsed with QDateTime::fromString and an appropriate format string.  Link:<http://doc.qt.nokia.com/4.7/qdatetime.html#fromString>
