How to keep track of real time ?

[Anonymous_Banned275]

I am seeking an advise.
I am initializing a real time QProcess , in library hence no real GUI using , only QDebug.
The QProcess is practically blocking my main calling function.
For overall process / progress indicator , I can run QProgress bar, but would like to have better track of various timing.

Ideally something line "numerical progress bar ".

I am not that versed in "connect", however, it looks as one of the ways to accomplish "timing record".

What would be a best way to ask Mrs Google?
For what ?

Or is there an example , in C++ code ?
