Can I add timesamples to tx samples

Hi,
Considering we can get timesamples of rx samples from UHD in
metadata,can I add timesamples to tx samples,which would be send
together.
Thanks.

Sure thing!

This link points to some of the examples:

And here is a project that uses the timestamps to do TDMA:

Do the timesamples record the time rx/tx samples going through AD/DA in
USRP(FPGA)?

Maybe my last replay is ambiguous.In metadata,the the time value of
rx_sample tags was get by the command “time.time()”.Does it mean that
the actual time recorded in tags refer to when the sample goes through
AD in USRP with the clock in USRP?
