[aklug] Re: OT: Windozs time syncronization

My dad had a best friend that was a carpenter in his youth. When he was 18,
he built a canopy for his pickup truck, 2x4 construction with cedar shake
siding. Dad threw a tarp over his pickup bed.

Somewhere between 'true Royce form' and 'lazy admin' JP is the path the
well traveled. LOL

Good research Royce... I didn't realize ntp in windows was so sloppy. maybe
that is why I rely on 'robocopy /fft' and 'rsync --modify-window' so much?
