Re: [chrony-dev] SW/HW timestamping on Linux

Yes, I think offset covers the delayAsymmetry feature. The other two, latency for tx and rx would be very, very helpful. Any chance of that happening prior to release?

Thanks,

Btw, it might be good for Chrony to support configuration for corrections similar to what is discussed in that thread:

 delayAsymmetry - corrects for any asymmetry between the Rx and Tx paths
 egressLatency  - corrects the transmit latency at the MAC/PHY
 ingressLatency - corrects the receive latency at the MAC/PHY

I think the offset option in chrony is basically the same as
delayAsymmetry, but there is nothing like the other two options. They
could be specified in the hwtimestamp directive and they would be
useful on servers.
