The above requirements are met using the setters described below.
-CT_POLICY_EVAL_CTX_new() creates an empty policy evaluation context. This
-should then be populated using:

+CT_POLICY_EVAL_CTX_new() does the same thing as

issued in the future. RFC6962 states that "TLS clients MUST reject SCTs whose
-timestamp is in the future". By default, this will be set to the
-current time (obtained by calling time()) if possible.
