We know that for the EMA it would restart the clock if a Request for Clarification was issued.
So even if the MAA was valid, the EMA would reset the clock on a clarification request. And the MRA used to follow the EMA regs, so likely still does unless somebody can show otherwise.
And no, I never said the confirmation date. It would be the date the RFC was returned by NWBO. That starts the clock at the next submission slot, Mar 4.
