rsync doesn't use timestamps.  It looks at the entire file contents for 
both source and target, and performs some pretty hefty computation on 
them.  Thus, it only gives a speedup when copying files over a slow link 
between two machines.  It's great over the Internet, not so great over a 
fast LAN, and useless within a single machine.
