Usually it changes them then reverts them.
E.g.:

    git stash
    git pull
    git stash pop

all the files modified locally but not in the pulled change will have
a new timestamp but the same old contents.  Since these are separate Git
invocations, I don't think it would be correct for Git to reset the
timestamp to some earlier value.
