Thank you.  I see what you mean now and I confirm that I can reproduce
this behaviour.  In particular, saving the smoothed view (as
attached), one can see that the time has been zeroed, although the two
time-step indices have been correctly preserved.  It doesn't seem
right, and I don't know how to fix it.  Let's call it a bug.

I thought this might have been easy to fix, so I had a quick look at
the code in Plugin/Smooth.cpp.  The body of the execute method is very
short, so I guess most of the work is being done elsewhere, but I
wasn't able to follow the trail from there.
