Clock not in sync

Hi All,

We are facing an issue of clock sync between our rhel 7.6 nodes configured in vmware 6.5.
We have checked the same with enabling/disabling Chrony,NTP services and also by setting up local time.
We still are getting time difference which is gradually increasing and when the load of boxes increases the difference increases rapidly which is impacting our performance testing.
Kindly suggest resolution. :)
