Since .ts is the only timestamp in the ZC api, and the igb timestamp is
a 20bit value, if you set the ts field to the hardware timestamp then
there is no record of the actual date/time of arrival of a packet.  Is
this correct or am I missing something?

Using DNA you have a function pfring_set_device_clock  which was
useful.  Setting the clock to 0 at the start of a measurement meant I
didnt have to deal with clock wrapping.  Is there anyway to clear the
clock using ZC?

Thanks
