    @fhueske I've addressed most of the points, however there is a thing that 
is not clear to me yet. So far, the procTime() function generates a timestamp. 
My understanding is that this is not correct, and it should be something else. 
could it be a default timestamp (e.g. epoch)? the actual timestamp normalized 
to the second? what is the best option in your opinion?
