RE: No Escape

Thanks for that clarification.  This is actually how I'm using Tardis, with
my Linux box as the ntp server.

Although I'm not 100% sure, it looks like Beaglesoft's ClockWatch behaves
similar to npt clients on Linux.  http://www.beaglesoft.com/  Can someone
who actually has a clue look over their tech-specs?

Later,
Rob
