People will shortly begin telling you that Windows Time Service does
not "synchronise" your clock at all. It just steps it and lets it
run as it did. And it steps once a day or once a week or so.

Note that ten minutes per day is nearly 7000 PPM. Standard NTP bugs
out at 500 PPM. People are also going to begin telling you to look
for lost timer interrupts and/or swap motherboards.
