I think it probably happened between the PJS and HoO timeskip. I mean, Percy still remembers his life, he looks a little older(his 16th birthday probably was one or two months ago and after this, he's probably going to get captured by Hera) and he was still on Long Island. Also, he said the croc was terrorizing Long Island and ate one of their pegasus. Which means he was still at camp and probably tasked himself to find the croc.
