Thanks for your confirmation that the signature is good.

But I was not saying that the key has expired *today*. I was saying
that the key had already expired at the time it was used to create the
signature: the key was used to create the signature several weeks
*after* it had expired.

Or was the expired key not actually used to create the signature and
the note was irrelevant noise from GnuPG?

That's one reason why I only got around to asking about this now -- it
didn't seem urgent. The other reason was that the key had only expired
a few weeks before the signature was created. If it had expired years
before I might suspect that the key had been compromised.

Best regards,
