Package: libgnupg-interface-perl GnuPG::Signature reports the time that a given signature was created, but does not provide information about when the signature is scheduled to expire. Not all signatures have expiration dates, but those that do, it's a pretty relevant piece of information ;)
http://tools.ietf.org/html/rfc4880#section-5.2.3.10 The attached patch adds support for signature expiration, and standardizes/clarifies what the expiration should look like (undef) in the event that there is no expiration for a key or a signature. --dkg
