That's a while ago! I have to see if I still have those scripts around as my explanation above is not even to me very clear :-) ... x = time y = offset compared to my system (a xen vps in a datacenter) color = delay It's a couple of java classes doing sntp calls in parallel. Then it's just a matter of averaging and such.
