Configure the System Time Zone and Time Synchronization Settings
After you deploy the vCenter Server Appliance, you can change the system time zone and time
synchronization seings.
When you deploy the vCenter Server Appliance, you either use the time seings of the ESXi host on which
the appliance is running or you congure the time synchronization based on an NTP server. If the time
seings in your vSphere network change, you can edit the time zone and time synchronization seings in
the appliance.
I If the vCenter Server Appliance is using an external Platform Services Controller, you must
congure both the vCenter Server Appliance and the Platform Services Controller to use the same time
synchronization source. Otherwise, authentication with vCenter Single Sign-On might fail.
