Synchronize the vCenter Server Appliance Clock with an NTP Server
Before you deploy thevCenter Server Appliance, make sure all machines on the network have their clocks
synchronized. Unsynchronized clocks can cause installation and authentication errors.
On systems that are joined to a Windows domain, the vCenter Server Appliance clock is synchronized
automatically with the domain controller. On other systems, you can enable synchronizing the clock
through VMware Tools. As an alternative, you can use this procedure.
Procedure
1 Open a Web browser and navigate to thevCenter Server Appliance Management Interface
(https://vCenter-Appliance-Address:5480/).
2 Log in as root.
3 From the vCenter Server tab, select the Time subtab.
4 Select one or more of the available options.
Option Description

appliance to synchronize with an NTP server directly.

Active Directory synchronization
This option becomes available only if you add the appliance to an Active
Directory domain. If you select this option, none of the other options is
available.
