<DIV><FONT size=2>As far as I can tell, at the moment not even libpcap supports
nanosecond timestamps. The code seems to just contain the magic number, but
nothing has been done to support files with that magic number. Please consider
that one of the problems that comes to my mind is that there is currently no API
in libpcap that can tell you if the file was saved with the usual microseconfs
timestamps or with nanoseconds timestamps. So even if support for that magic
number is enabled, libpcap-based and WinPcap-based applications would have
a hard time distinguishing between nano and microseconds trace
files.</FONT></DIV>
