It's useful to omit the timestamp outside of git too. Source-based package
management systems generally store a URL from which to fetch a source
tarball, and a hash of that source tarball to ensure it hasn't been tampered
with. It's nice to be able to use a gitweb URL like

  http://git.kernel.org/?p=git/git.git;a=snapshot;h=e5af0de202e885b793482d416b8ce9d50dd2b8bc;sf=tgz

as the tarball source, and still be able to verify its integrity against a
prestored hash.

Cheers,

Chris.
