Hey Gary,

In my lab, with PTP-aware switches/network cards, but no tuning, I'm able to get 60 nanosecond offsets as measured by the offsets of the PPS-out on my grandmaster vs my PTP-client.  I don't yet understand the failure modes and falseticker-like detection options for PTP to be comfortable deploying it yet, especially since 1 microsecond vs 60 nanoseconds isn't yet important for me.


Thanks,
