DescriptionSome of the ESXi hosts had incorrect date configuration which could cause VM issues under the following circumstances
1) The VM was on the "bad" real host,
2) Vmware tools is installed (default is to be), and
3) The tools configuration set to sync with real server (default is NOT)
The issue would be the windows time system and the VMware tools system both attempting to update the time to a different (in some cases hours apart due to time zone issues).
Fix: Disable tools from setting time (restore the default), and fix the NTP config on the esxi boxes.
