In a related note, you can use stream tags to get a precise timestamp of every sample in the stream: http://gnuradio.org/cgit/gnuradio.git/tree/gr-uhd/include/gr_uhd_usrp_source.h#n59 > > However, this only shows the end time when I stop the flow graph manually. > Is there a way in gnuradio that can read the system time during the running > of the program? > > For example, the flow graph begins to run and receive --> after 1000 > samples have been received, output system time --> the program continues to > run.... > > In addition, how to stop a grc flow graph automatically? In the non-gui mode, you can set the option "run to completion". The flow graph will exit when the flow graph is "done". Done can happen for example when gr_head block sees all N inputs.
