Perhaps the solution is to use an 'install' program which only copies files if they have changed. Rsync is an example of a program which can do this.
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.
