gpg: Signature made Sun 04 Dec 2011 09:48:28 PM MST using DSA key ID B0413BFA
gpg: Can't check signature: public key not found
Even back-dated about 6 hours. Nice.
Edit: Nevermind. The forum is using UTC for the time-stamp on posts.
Edit2: See, I was really first:
-----BEGIN PGP SIGNED MESSAGE-----
When one sign a text with private key, he can prove, that he had a text
If one will add a timestamp from some block
one can prove that he have that text before any other.
-----BEGIN PGP SIGNATURE-----
Version: GnuPG v1.4.6 (GNU/Linux)
-----END PGP SIGNATURE-----
To go back any further, I would have had to back-date my signing key as well. Then there are archaeological considerations like: should I use the Debian "Weak keys" just for extra detail?
