Of course. The kernel is a good place to start though. The date in
uname -v isn't particularly helpful at the moment. Userland issues
are clouded by the fact that each piece of software is discrete. Also
we have 'ident' which can tell us about any particular piece of
software. We could almost do a ident-extract-latest-date in periodic
to deal with userland.

The date after the 5.0-CURRENT bit. (Proof of concept, not final uname
format).
