That would be a bug then.

That's true. But you actively need to do something to make elements in a
pipeline have different base_times (and clocks). Do we really do this and do
elements in this case need to know about the other 'time domain'?


It sounds like you want to make the POSITION query it more generic so that it
can return more than just stream_time.
