I think I know what's happening ---you use TeXShop as your DVI  
viewer, so each time you issue the command View in Emacs, even  
without a change in the DVI, Emacs goes all the way dvi->dvips->pdf,  
and your PDF has a new time stamp.

On the other hand, if the DVI really changes, TeXShop doesn't update  
the PDF because it is set to be a PDF viewer not a DVI viewer.

I bet that if you use pdflatex in Emacs *and* use TeXShop (not  
Preview) as your PDF viewer, TeXShop will update your PDF.

Best,

Axel
