Why would you think that? The semantics of x= say nothing about those
Signature expiration in seconds-since-1970 format
as an absolute date, not as a time delta from the signing
timestamp. Signatures MUST NOT be considered valid if the
current time at the verifier is past the expiration date.
If you *want* the semantics to mean 'don't count on being able to
verify this message after this date', that's fine, but you need to
ask the WG to change the document for that to happen.
