Re: [Discuss-gnuradio] If uhd support a more precise In band signaling timestamp in the resolution 1ns or 10ns?

I recently learn the uhd project which contain a double type timestamp

precise timestamp from usrp hardware or it just an interface change to
meet other hardware? For now, I want to measure the time of flight to
count a distance, so the timestamp should be as precise as at least
100ns to meet my need.
The UHD will give you sample times which are accurate to 1 cycle. On
the USRP2 this is 10ns.
