The pcap_timeval has units of microseconds only, so that is the limit for how precisely tcpdump can read/store time from pcap files. I believe that the ntar format may do nanoseconds. However, the more relevant question is, can your OS and hardware provide you with nanosecond resolution timestamps in your packet capture interface. -- ] He who is tired of Weird Al is tired of life! | firewalls [ ] Michael Richardson, Sandelman Software Works, Ottawa, ON |net architect[ ] mcr () sandelman ottawa on ca http://www.sandelman.ottawa.on.ca/ |device driver[ ] panic("Just another Debian GNU/Linux using, kernel hacking, security guy"); [ - This is the tcpdump-workers list.
