Does that imply that a CA that signs a cert that is supposed to be
valid for 2yrs using an intermediate cert that is valid for 20 months
essentially makes a cert for 20 months only because for the remaining
4 months the cert will be invalid?
The application will, of course, use whatever gnutls supplies for cert
validation so when the cert does not validate in gnutls it will not
validate in any app using the library unless the authors went out of
their way to examine the certificate chain manually.
