Especially given that there isn't necessarily a guarantee that the time stamps reflect the exact arrival time of the 
first bit - or the last bit - of the packet at the receiver's network adapter, or that it reflects *anything* other 
than the time when the hardware, software, or firmware that timestamps the packet first sees the packet (which could be 
at some point in the host networking stack).
