The time difference between sending and reciving.
Thanks for the idea!
We can do that, but what about using RTnet+RTcap (+Ethereal as a capturing tool) on those PCs without a third station?

What timing? On the cable?

Do you have a chance to attach a third station as a sniffer to your
network (works best with one of the rare 100 MBit hubs...)? Then
grabbing the traffic with RTnet+RTcap on that box would give you a good
impression with accurate timestamps (in the order of IRQ latencies).
