Hi, I am using "openssl verify -CAfile <ca> <cert>" to verify the certificate. It's been running as expected. Recently I started to run this command on a different x86 platform. What I found is the the first few times I always got: error 9 at 1 depth lookup:certificate is not yet valid Then I waited 10 min and reran the same cmd and got "OK". I am puzzled by this. Is this a some timing issue? My openssl version is: OpenSSL 1.0.1e-fips 11 Feb 2013 David
