Bug description:
  Ubuntu shall be secure by default, therefore utilize Network Time
  Security (NTS), as time is the trust anchor for many cryptography
  related processes (e.g. certificates).

  NTS was previously enabled in chrony (LP: #2084585) and comes pre-
  installed in certain Ubuntu cloud images. Still, in Ubuntu
  Desktop/Server and other generic Ubuntu images we rely on systemd-
  timesyncd (without support for NTS [1]). This leads to a situation
  where we have to maintain two time-daemons in "main", while still not
  using NTS on most systems.
