I've avoided getting into this till now because I felt I needed to know how you were using the terms to see what you mean... there are a lot of possible ambiguities in the way you have expressed these ideas.

Sometimes the term includes the Oort cloud, and sometimes it is used to only go out as far as the heliopause. BUT, my point is that unless you are working on some theory that there is an aether in which all of these things move, the idea that all of these things could be said to be spinning in some uniform way is not a physical description. You could make some kind of Ptolemaic argument that there is some outer sphere driving everything else that accounts for some calendrical differences, fine. No need to argue against that unless you then try to imply a physical connection. There is no aether, and the solar system as a whole does not spin (though I like HUb' 's thought that once per galactic orbit (200 million years) or Galactic equator crossing (25,000 years roughly) you could say that some kind of rotation has occurred.
