packet arrival time?

[liorme...@gmail.com]

Hi

This is not strictly games, but there're a lot of smart folks here so
maybe you can help me out. I'm working on an application which needs
synchronization between machines, which are going to do using tcp/ip
or udp. the problem is that if we will build ON TOP of the regular
socket mechanism available in C#, for example, we will know when the
packet arrives to us, but not really when it arrived at the network
card.

how can we find out when the packet arrived at the network card,
without needing to rewrite winsock?

thanks much for ANY idea,
Lior
