Our group also needs a replacement for the keyword-expansion mechanism (we are using a nice little system, which allows for each executable produced to query it about the source-code-files involved in it, which is especially useful for testing and development, where many versions of many files float around (and perhaps some shouldn't)). The principle solution seems quite clear to me: Adapt the pre-commit hook, so that files are scanned for the keyword, and apply the keyword expansion then before the actual commit. Better than just the date, it would be greatest to be able to put also the SHA1-ID of the commit into the file, alas this is a bit complicated, since it's a pre-commit hook; However it seems necessary to have in the repository really the actual file content, not "modulo some modification", due to the distributed character of Git repositories (everybody should have the same file-timestamp), and so a post-commit hook shouldn't be used. So well, using the previous SHA1-ID should be a reasonable approximation.
