I think it will also be very useful

I went through the stream tagging pdf.
The tags from source has time,freq and rate.
I am interested in insuring that transmitter sets a particular frequency of
transmission ie Tx_Next_freq and time at which the transmitter starts
sending data packets at an instance.
The set_command_time as you s
"how can i make the usrp send its time when configured for synchronization?"
I might be misunderstanding the question, but here's an answer. The USRP
source outputs stream tags on the first sample when streaming. The three
tags are 1) rx_time 2) rx_rate 3) frequency. Using (1) and (2), you

I think i can use set_command_time (which i guess set the next time of
transmission/command?).
how can i make the usrp send its time when configured for synchronization?

"XML_RPC block in the new gr-extras"
XML_RPC would have been subject to the same limitations. It could only
call set_time_next_pps if set_time_next_pps was in the uhd_sink/source
blocks. Maybe you can update them to include the function.
Let me ask a more fundamental questions - why do you want
so do we have any other block to do that. I did'nt find XML_RPC block in
the new gr-extras

uhd_control block supports only a subset of usrp-functions (exposed
through gr-uhd) e.g. "set_command_time", set/get_gain/freq etc BUT
currently it doesn't support "set_time_now()"

thanks for the clarification
so i checked the new grextras wiki it has uhd_control block i guess that
can be used for this job.

The GPSDO can provide an "internal" 10 MHz/1 PPS signal. I'm not sure if
that's what you meant or not:

AFIAK, you cannot set the time of a USRP with a message. You may be able to
use the XML_RPC block in gr-extras to call the function if it is expos
