For any Directory Services, especially those with Kerberos, it's less important that the computers all have the "correct" time than it is that they all have the same time.

Click next to proceed. In the Confirmation tab, verify the selections and click on the Install button. You may or may not select the option "Restart the destination server automatically if required". It is always a best practise to restart the server post installation.
Once done, it will start the installation process and you can check the same in the Results tab. Once the ADDS role installation completes, click on the option "Promote this server to a Domain Controller" highlighted in below image. Alternately, you will see a notification flag next to the Manage menu.
From there also you can select "Promote this server into a domain controller", this will start the configuration process. It will open the "Active Directory Configuration Wizard". Now, from the Deployment Configuration tab, select "Add a new forest" as I am configuring new Forest and it is my first domain controller.
Provide a Root Domain name , mine is "VirtualGyanis. Com" you have to put your domain name here. Then, click on Next to continue. In the Domain Controller Option tab, select a Forest functional level and a Domain functional level as per your environment.
The domain controller with the PDCe role should sync with an external, reliable time source. This could be an internet time server, a hardware time-keeping device, or an internal NTP server that isn't part of the domain.
From there, the other domain controllers in the domain will sync their time from the PDCe. Finally, workstations and member servers will sync their own time from an available DC. If this all functions correctly, time across the domain will be in sync with a margin of error of less than a few seconds.
The preferred method for configuring Windows Time is with the w32tm command. This example command will configure the PDCe to use both time. For the rest of the servers in the domain, you would use this command to configure them to sync from the domain hierarchy.
If you notice any of the above, you'll need to do some troubleshooting. Depending on how the issue appears, you'll need to either review the configuration of a specific member server, its nearest DC, or the PDCe.
Domain members synchronize time with domain controllers, which in turn synchronize time with the domain controller running the PDC emulator role. The PDC emulator of the forest root domain is at the top of the domain hierarchy, and as such configuring this domain controller to synchronize time with the domain hierarchy is invalid. However, this approach has drawbacks. In addition, if the PDC emulator goes offline, domain members will be unable to synchronize time.
A better approach is to configure the PDC emulator to synchronize time directly with an external time source. Alternatively, you can configure another device within your domain to synchronize time with an external time service, and then configure the PDC emulator to use your internal time server as the authoritative time source.
