You can configure the time synchronization settings in the vCenter Server Appliance to be based on an NTP server.

Prerequisites

Set up one or more Network Time Protocol (NTP) servers in the vCenter Server Appliance configuration. See Add or Replace NTP Servers in the vCenter Server Appliance Configuration.

Procedure

  1. Access the appliance shell and log in as a user who has the administrator or super administrator role.
    The default user with super administrator role is root.
  2. Run the command to enable NTP-based time synchronization. 
    timesync.set --mode NTP
  3. (Optional) Run the command to verify that you successfully applied the NTP synchronization. 
    timesync.get
    The command returns that the time synchronization is in NTP mode.
