gpg: Note: secret key [...] expired...

[Keine Eile]

Hi list members,

I have a revoked private key in my key ring, which I replaced with new one. I really do not want to discard this old key, for what I think good reasons. Is there a way to let gpg ignore this key or suppress this this¹ notification?
