[Discuss-gnuradio] timed_commands broken (gr-uhd / 3.7.1)?

[Marcus Müller]

Hello list,

after a lot of working, I finally came around to write a minimal example 
to show what does not work.
To make it short: from python, calling
src = uhd.usrp_source(...)
[...]
src.set_command_time(uhd.time_spec(<a second in the future>))
src.set_center_freq(1e9)
src.clear_command_time()
does _not_ issue the tuning request a second in the future; it is 
executed right away.
However, the next get_time_now() call happens a second delayed.

The complete test can be found under 
https://gist.github.com/marcusmueller/6251825 or cloned via
git clone https://gist.github.com/6251825.git

Could please someone verify this problem is specific to my system?

Thanks in advance,
Marcus
