A new property called 'clock_synchronization' was added to the host object. The CLIs and APIs have been updated. The default value for 'clock_synchronization' is 'ntp'. The 'enabled' property was removed from the NTP and PTP objects and the CLIs/APIs updated accordingly. The GUIs for these objects were also updated. See SB https://storyboard.openstack.org/#!/story/2006499 for more information. Some code is still in pending review.
