Thorsten Glaser has found the following issue with gnutls 3.5.8,
reported as <http://bugs.debian.org/853732>:

----- Forwarded message from Thorsten Glaser <tg at mirbsd.de> -----
The build fails in the pkcs7 testsuite because of a wrong date;
the testsuite fudges to 2038-10-12 00:00:00 localtime:

(pbuild22064)root at tglase:/tmp/buildd/gnutls28-3.5.8 # openssl x509 -noout -text -in doc/credentials/x509/ca.pem | fgrep Not

            Not After : Oct 12 08:36:33 2038 GMT

The fix is easy:

For simplicity's sake I'd simply go for datefudge -s "2038-10-13". ;-)

I could not reproduce the build-error on amd64, but the Gnutls bug is

On amd64 this correctly succeeds...
datefudge -s "2038-01-19" src/certtool --inder --p7-verify --load-ca-certificate ./doc/credentials/x509/ca.pem --infile ./tests/cert-tests/data/full.p7b
... and this wrongly fails:
datefudge -s "2038-01-20" src/certtool --inder --p7-verify --load-ca-certificate ./doc/credentials/x509/ca.pem --infile ./tests/cert-tests/data/full.p7b
