title: libpcap timestamp resolution
body: <p>I am using python module pypcap (simplified object-oriented Python wrapper for libpcap). I am having troubles with timestamp resolution. In my pcap file I can see my packets have nanosecond precision, but when I parse the pcap file in python and extact the timestamp from a particular packet, it only has microsecond precision?</p>
  
  <pre><code>import pcap
  for ts, pkt in pcap.pcap():
      print ts, `pkt`
  </code></pre>
  
  <p>ts has microsecond precision. I want nanosecond precision, any ideas? Thanks</p>
