If I may interject here - this is where ntpviz is akin to singing 'I was 
blind, but now I see'. For me it was revelatory, I thought my nifty Raspi 
Pi was kicking out some slick ntp riffs, and I was badly mistaken. 
Visualizing what's happening with graphs reveals so much more depth to 
what is going on. My timeserver(s) are  an order of magnitude "better" 
than what I'd initially put together several years ago.

Highly recommended.
