Yes and then again, no

Yes, if you are going to use the DC as a time source.
No, if you don't use the DC as a time source.

All that is required is that all domain computers are within 5 minutes
of each other, how you do this is up to you. Best practice is for the
DC with the PDC emulator role to get the time from an external time
server and all other domain computers to then, ultimately, use the PDC
emulator DC as their time server.

If you can ensure that all domain computers are within 5 minutes of
each other, then you shouldn't have problems.
