But without hardware time stamping, you are not going to get very good
synchronization performance.

Here is another simulation idea you could explore. It would be very
interesting to be able to test the BMC in a simulated network, and to
test the clock servos as well. Take a look at Miroslav Lichvar's clock
and network simulator to get an idea of what can be done.

It would be a fair amount of programming, but you could then simulate
the hardware timestamping as exactly as you wish.
