"@command{tlsdate} sets the local clock by securely connecting with TLS
to remote servers and extracting the remote time out of the secure handshake.
Unlike ntpdate, @command{tlsdate} uses TCP, for instance connecting to a
remote HTTPS or TLS enabled service, and provides some protection against
adversaries that try to feed you malicious time information.")
