Re: Date/Time accuracy (was Re: First TOM1 image under Rob's Software)

Hey Robert,

The reason his machines (Linux) agree with his watch as I setup a NTP server
(matt) and 2 clients (chipper and bill) when I was getting my software running
on them.  Works great.

I just didn't tell Tom that ;-)

Cheers,
Rob
