I'm not so sure about the whole thing having any connection with Arc of Time yet. It might very well turn out that the messing with Erzas time comes from the Eternal Flame rather than the being who froze the whole area.

The brocoli man did say that the frozen people are still alive. If the Flame (or it's source) is something sentient it might still be able to affect it's surroundings a little despite being frozen. The flame might even turn out to be the reason how the people are still alive, despite being deep frozen for at the very least several days.

Or it might turn out that Erza was never turned into a child and all this is only happening in her head (the mental/telepathic contact or somesuch with an utterly alien being causing some side effects or maybe her consciousness is being probed). After all noone saw Erza as a child yet.
