You can enable time synchronization on your vRealize Orchestrator deployment with the vRealize Orchestrator Appliance command line.

You can configure time synchronization for your standalone or clustered vRealize Orchestrator deployment, by using the Network Time Protocol (NTP) communication protocol. vRealize Orchestrator supports two, mutually exclusive, NTP configurations:
NTP configuration Description
ESXi This configuration can be used when the ESXi server hosting the vRealize Orchestrator Appliance is synchronized with a NTP server. If you are using a clustered deployment, all ESXi hosts must be synchronized with a NTP server. For more information on configuring NTP for ESXi, see Configuring Network Time Protocol (NTP) on an ESXi host using the vSphere Web Client.
Note: If your vRealize Orchestrator deployment is migrated to a ESXi host that is not synchronized to an NTP server, you can experience clock drift.
systemd This configuration uses the systemd-timesyncd daemon to synchronize the clocks of your vRealize Orchestrator deployment.
Note: By default, the systemd-timesyncd daemon is enabled, but configured with no NTP servers. If the vRealize Orchestrator Appliance uses a dynamic IP configuration, the appliance can use any NTP servers received by the DHCP protocol.

Procedure

  1. Log in to the vRealize Orchestrator Appliance command line as root.
  2. Enable NTP with ESXi.
    1. Run the vracli ntp esxi command.
    2. Run the vracli ntp apply command.
      The ESXi NTP configuration is applied to the vRealize Orchestrator deployment.
  3. Enable NTP with systemd.
    1. Run the vracli ntp systemd --set FQDN_or_IP_of_systemd_server command.
      Note: You can add multiple systemd NTP servers by separating their network addresses with a comma.
    2. Run the vracli ntp apply command.
      The systemd NTP configuration is applied to the vRealize Orchestrator deployment.
  4. (Optional) To confirm the status of the NTP configuration, run the vracli ntp status command.

What to do next

The NTP configuration can fail if there is a time difference of above 10 minutes between the NTP server and the vRealize Orchestrator deployment. To resolve this problem, reboot the vRealize Orchestrator Appliance.
