No disrespect, but this is part of the problem, few end users probably have experience with Scilab or GNU Octave.
Again, I think the end user may have been and after thought
Epoch time is not so usable when you are Logging over days and you want to easily make comparative readings.
Each person has their strengths and abilities, and I for one think the end user need to understand the inner workings of this meter to properly and safely use it. Case in point, wrong setting can and will make AC Voltage measurements low.
Just need to understand there are many different level of users of this device.
