I'm with you -- it would be much easier to checkout with something like
"--restore-time" or "--touch" if it were implemented.

The problem is that after `git clone` there are no original timestamps.

I gave it a thought and came out with the following code to correct times in 
git checkout before packing to orig.tar:

    for F in $(git ls-tree -r --name-only HEAD); do
        touch -d "$(git log -1 --format="%ai" -- $F)" "$F"
    done

What do you think?
