Yes, I appreciate that requirement.

Both Windows and Linux, if incorrectly configured, can have problems with
lost interrupts. I have been unable to reproduce the lost interrupts
problem with recent versions of Windows (XP Pro SP2). I would recommend
NTP over W32time for the best timekeeping with good monitoring and control
functions.
