Thanks Dave,

I've been using gawk to extract the records for each server and Gnuplot 
to plot offset, delay and dispersion for each day..  I stumbled across 
the awk scripts while trying to find a different awk script entirely 
with the intention of recycling pieces of it do some simple statistical 
studies that your scripts already do

The existing summary.sh script does not appear to be entirely Y2K 
compliant;  if I'm reading it correctly, it's still looking for 
peerstats and clockstats in the 20th century.  It also appears to expect 
the stats files in the same directory where it and the awk scripts 
live.  I think I can fix that and, perhaps, also modify it to use 
Gnuplot.  I'll be happy to share if I can get it working.
