Sounds about right. If you are getting timing from something like GPS, you can measure that offset. If you are setting your clock from the net, your clock will be off slightly. But that error cancels out when somebody on the net gets time from your system. > To make a difference that might be noticeable I think you would need to see > at least some queing on Ethernet, ... the choke point is usually the ATM > device though as the ethernet link is the faster link That's an additional problem area. It's what huffpuff is designed to avoid. It's easy to tickle it. All you have to do is run a big upload (or download). It needs to be "big enough" which depends upon the polling interval. -- These are my opinions.
