With modern 100Mbit networks you have some chance to achieve this, but it's far from "guaranteed", and also I'm struggling to see how you will verify it.
Plus the PC itself will drift over time from the accurate time, not sure what modern PC numbers are, but back in 90's the PC RTC did drift couple of seconds per day, so you should resync often.
Overall if you *must* have all computers synced all the time, and you have no fallback/recovery plan, I have very bad feel about this, you probably shouldn't use PC and Internet for such task.
