 tlsdate: secure parasitic rdate replacement

  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, 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.
