That says what the high-resolution time counter's value is now, not 
what the value was when bufmod saw the packet (which raises another 
issue, namely that the time stamps you get out of libpcap might have 
nanosecond *precision* but they might not have nanosecond *accuracy*) - 
or are the packets in question not being captured by libpcap, so that 
you can use "gethrtime()" to time stamp packets reasonably close to the 
time t which they arrived?
