Really? You've got a really worrisome Active Directory domain, then,
especially if your DCs aren't syncing with each other ... Me, I'd fix
that domain first (and quickly), and then just let all the other
clients (Windows and Linux) just get their time from whatever DC has
the PDC emulator role, rather than introduce yet another server into
your mix to do something that your current servers should be doing.
YMMV ...

AD gets very, very unhappy if it's timestamps don't match between DCs.
