No problems. I think you have the wrong impression. You dont have to
change any files. The timed commands is actually an API call. This
called is exposed as part of uhd in the multi_usrp.hpp file. And its
also exposed in the gr-uhd gnuradio support wrappers. This means you can
use this API in C++ or python with the UHD gnuradio blocks.
