To configure Time Management settings in vCenter, follow the steps below:
1. Log in to the vSphere Web Client or vSphere Client.
2. Select the vCenter Server instance in the inventory.
3. Click on the Configure tab and select Time Configuration from the left pane.
4. Click Edit to configure NTP settings. You can add one or more NTP servers, and select the preferred protocol (UDP or TCP) and the authentication mode, if required.
5. Click Test to verify the NTP connectivity.
6. Click Save to apply the NTP settings.
7. Select the VMs or hosts to apply the NTP settings to, from the Sync Time with ESXi Host option. You can also select the preferred time synchronization source from the drop-down list.
8. Click OK to save the changes.
Once the changes are saved, the vCenter server will synchronize the time with the configured NTP servers, and the selected hosts or VMs will synchronize their time with the vCenter server.
