Also your "rachelbythebay" post is discussing exactly the problem I'm trying to solve with hardware - using software. You don't need to run NTPd at all if your computer hardware and infrastructure has solved the problem of "keep my clock accurate down to 10's nanoseconds." Also, there's another unrelated problem which is "how accurately does a user process running in a linux kernel get the current time?". That's a problem no matter what kind of hardware the kernel is running on (although hardware might assist with that as well).
