Hello,

I am capturing with dumpcap or tcpdump on a Linux machine.
Can someone provide me with some information/link(s) on
a) how precise the timestamps on an average Linux PC are
b) whether there are ways to improve the precision (OS wise or code wise)
c) a way of determining the timestamp precision of a given machine
d) what I should really have asked ;-)
What I'm interested in is not so much the absolute timestamp but the
precision of the delta between packets captured on the same interface.

Thanks
    Jörg

We are stuck with technology when what we really want is just stuff that
works. Some say that should read Microsoft instead of technology.
