test if ntpd can connect to 4460/tcp port
    
    A recently filed BZ report revealed that SELinux prevents the ntpd
    service (which belongs to the ntpsec package) from connecting to
    the 4460/tcp port when it is configured to use the NTS servers. The
    TC reproduces the situation.
    
    In order to support the NTS standart for the ntpd service, I believe
    that SELinux policy should allow the action. The TC looks for appropriate
    policy rules, port context and file context patterns.
    
    The TC covers BZ#2246805 and RHEL-15085.
