I quoted what is from Airbus itself. I am sure you have not seen the Airbus reply yourself. You are still confusing two issues Timing does not start from FADEC switching on ignition but from manual selection of Engine mode selector to ignition and . However you don't need to time it because: Reproducing Airbus document
Do I read the chronometer to monitor the 30 seconds? Not required
But this is not same as what you are saying.
