Egad - rsyncing between different OSes and neither OS is *nix.
That's pretty rare. Although Mac OS X is technically *nix I guess.

Rsync doesn's care about creation dates - only modification dates.

Right. Where are you running this - on the Mac and copying to a
mounted Windows filesystem? If so, then you are probably falling
victim to the 2 second granularity mentioned in the cited section
in the FAQ, and roughly half your files will be getting re-synced
every time if you are transferring files to a Windows filesystem.
Try adding --modify-window=1
