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.
