Thanks Ian
that just answered what I found during research .
It is really a shame, such a super piece of hardware and no way of getting the total print time out of it.
I am working and building octoprint servers, There it is a feature ever there since I can think;
even more with the "print time genius" plugin you get more precise predictions of print time already during print, so if you change parameters on Slicer even if not printed to the end you already can predict total print time
