You most likely want to use gst_pipeline_use_clock() though, as
otherwise GstPipeline will still select a clock itself when changing
state from PAUSED to PLAYING. Which is usually when clocks are selected
and also when clocks are advancing in the GStreamer context (i.e. the
running time advances, but for some clocks they also don't advance at
all in PAUSED like Nicolas says).
