	I found #8 on David Mills's list particularly useful:

> Hi,
> 
> I've been looking for info on how accurate NTP can be. I've looked in various NTP related sites and still not quite sure.
> 
> Say I have a LAN like environment with delays in the range of 10s of ms. How accurate a time can I get from NTP, assuming I have the appropriate HW clocks on my host ?
> 
> Say I have a corporate network like environment, relatively segregated from the Internet at large, with delays in the range of 100ms. How accurate a time can I get ? 
> 
> Say the delay range goes upto 500ms, how accurate can the time be ? 
> 
> Any pointers to specific experiments or data would be appreciated.
