Phi-Bi

I think it's probably a couple months. the time passage is always a bit wierd, but I think the area where it matters most is when you're stuck up north. because a pretty substantial time has to pass over the whole thing for the entire city to get majorly renovated and the lake to be cleaned etc, and yet only a few days can pass between getting samsons badge and surf, and getting waterfall and going into the WTC with Titania, which is a massive chunk of stuff.
