I think decision of when the ship will be commissioned once the ship is physically largely complete is a political one. The ship could be commissioned as soon as she ran her sea trial and proved herself seaworthy, which can occur within 1-2 month of the ship being ready to sail for the first time, Or the PLAN may not formally accept her as an operational warship until it is fully satisfied that not only is the ship fully functional, but the doctrine associated with operating is proven as well. I think the commissioning date will be much closer to the ship being shown to be seaworthy than the ship being ready to fight.
