Stone accumulation is calculated according to game clock and time passing between events logged when you interact with Joachim, which is why you get free stones when you get the abyssites to extend time. It is already known that game clock is bound to real-life clock (a formula is applied to sysclock value). Unless they change time on the servers before launching the game services, they will recaclulate and you'll get the free stones.
But all that doesn't really need to be said, as SE already announced stones will accumulate during this crisis.
