SCO Unix and ntpdate

[Brett I. Holcomb]

The observations may have a solution in them <G>! 

I'll check all this out with our IT people.  The Unix box came with a 
timekeeping system and our IT people have not ever worked with Unix.  I 
have a long time ago so I got called!  

I didn't run xntpd because I thought it was there to act as a server.  
However, I'll check it out more tomorrow.

Thanks.
