I don't find the reference right here, but of the top of my head git 
changes modification times when checking out a branch, but keeps it when 
checking out a commit. But the real problem is the hosting services, and 
while we certainly can file bugs on github or gitorious, we also have to 
live with them.

We just had a thread on the github tarballs with the unreasonable names 
like 1234fcd; no extension... modification time is not the only problem
