The log files suggest otherwise.

Yes, I also find it difficult to accept that a crystal would change by
that much, which is why I didn't immediately just say "faulty hardware".
I just checked chrony and it does not appear to be available for Windows.
In any case, this system worked correctly before with ntp, so there's no
need to change. Work is in progress, and I will report back.
