   Dear Sir,

   I have a question. What on earth the clock frequency does the Wireshark use for timekeeping?

   For exmaple, the basic frequency of my PC is 1.8GHZ. So it's cycle is 1/1.8GHZ=0.56ns. Does it mean that Wireshark can get    

 

   the time resolution of 0.56ns?

   But why the Wireshark's time resolution is 1us?  Help me, thanks a lot!
