tmnxPtpNeighbMonTimeOffFrMaster

The value of tmnxPtpNeighbMonTimeOffFrMaster indicates the current
offset of the local PTP clock from a master PTP clock, calculated by
the local clock, as per IEEE Std 1588-2008, section 11.2 when Monitor
Receiver has been enabled on a given port.
              
It represents the 'instantaneous' value of calculated time offset
from a master PTP clock, using timestamp information from the most
recent exchange of sync and delay request/response messages.  There is
no filtering applied to the received sync and delay response messages,
and there is no averaging of this calculation over multiple exchanges
of sync and delay request/response messages.
              
The time that this offset was last calculated is provided by
tmnxPtpNeighborMonTimeLastCalc.
              
The active CPM calculates this offset each time the local PTP clock and
a master clock exchange sync, delay request, and delay response
messages.  The standby CPM does not calculate this offset, returning a
value of 0 for this object.
              
If PTP sync and delay request packets have not yet been exchanged
between the local clock and a master clock, both
tmnxPtpNeighbMonTimeOffFrMaster and tmnxPtpNeighborMonTimeLastCalc
return a value of 0.
              
Due to asymmetry in the latencies experienced by PTP sync and delay
request packets, the calculated offset from master may not be a true
indication of the actual offset of the local clock from a
master clock.  As well, due to packet delay variation in the PTP
sync and delay request flows, there may be significant variation
between successive calculated values of tmnxPtpNeighbMonTimeOffFrMaster.
              
The system only calculates the time offset between the local clock and
a master clock when tmnxPtpClockProfile is 'g8275dot1-2014 (3)' or
'g8275dot2-2016 (4)' and Monitor Receiver has been enabled on the
specific port.
