[Cialug] stuck load average and ntp?

[Tom Pohl]

Is this an old CentOS box?  I run CentOS a mix of version 4 and  
version 5 boxes and run ntpd started from an init.d script.

A dirty way to quickly get the date set correctly would be to run  
something like this with ntpd not running:
/usr/sbin/ntpdate -s -o 1 129.186.140.201

I apologize to ISU in advance for showing their IP (I don't think they  
like outsiders using their time servers), but it's the one I can  
remember :)
