Add 2 new parameters which set up the real time clock and enable the NTP client service. - ntp_enable_service: enables the NTP service if it's set on True (default) - real_time_clock_utc: sets the real time clock to use universal time (True) or local time (False- default) Change-Id: Ic6a613b2e0866784ab60ff78b2bfef6eba31a279 Implements: blueprint update-ntp-client Co-Authored-By: Paula Madalina Crismaru <pcrismaru@cloudbasesolutions.com>
