I have worked on this topic quite a bit to fix issues in git-p4. There is no direct way to get this $Id$ expansion in git, however you can use a simple pre-commit hook (alpha state, more a proof of concept that happens to work for me)

#!/usr/bin/env bash

for file in `git diff-index --name-only --diff-filter=AM HEAD` ; do
        perl -pi -e 's/(\$[ \t]*Id)(.*)([ \t]*\$)/"\$Id: git
".time()." \$"/e' ${file}
        git add ${file} > /dev/null
done
