Hello:

Does GNU Radio keep track of time, or sample count, or something similar as a 
flowgraph runs? How can I query the current "flowgraph time", from within my 
flowgraph, if such a thing exists?

More specifically, I have a Signal Source connected to a USRP2 Sink in order to 
generate a tone. Is there any way to query the Signal Source for how many 
samples it has created since the flowgraph started?

Thanks a lot.

Steve McMahon
