We currently have an AD topology in which we have one forest a root domain
and another domain in the forest. It is a placeholder domain topology. In
order to set up time synchronization we have enabled the PDC emulator in the
root domain to synchronize time with an outside time source. Is that all we
have to do or do we need to set the PDC emulator in the placeholder domain to
synchronize outside as well?

You need configure your PDCE to sync with an external NTP server. Child
Domain PDCE can sync with PDCE or any DCs from the parent Domain. Here is a
good article for your reference:

Placeholder domain? You mean a child domain or another tree in the forest? Either way, it's another domain in the forest, and it will *automatically* out of the box, follow the domain/forest time hierarchy, so in reality, there is nothing else you need to do. It basically works out-of-the-box.

Read more on the time service, how it works, how time sync works within a domain, and with child domains or other trees in a forest in my time blog, below.

Hello jskalicky,

Configure the PDCEmulator of the childdomain to the PDCEmulator of the root
domain as time source.

Best regards

This is NOT a requirement, but rather a suggestion.

Well, kind of, but not exactly,it depends on if that parent DC is in its own site or not. Based on the time domain hierarchy, any non-DC (workstation or member server), will sync up with the DC that logged it on, but if that DC becomes unavailable, the workstation's time service will query for another DC in its own domain in its own site. If a DC in the workstation's or member server's own domain DC is not available, it won't look outside the domain. A non-PDC Emulator in a child domain will sync up with the PDC Emulator in its own domain provided it's in its own site, and if not in its own site, it will sync up with a parent DC that is in its own site, preferrably the PDC Emulator if it's in its own site.

That was thinking out loud on top of my head. The article you posted has it in more detail, but the emphasis with a child DC syncing to a parent depends on its Site.
