We were a bit upset to see that it was going to take 3 days to dry.

It kept displaying that message at least an hour or two after we built it.
But today when we checked it again, roughly 23 hours later it had changed its message.

Edit: checking on it again, it seems like the minutes are ticking away way too fast.
...could it be that it's using the in-game time where a day only last a few hours? That's pretty confusing if that's the case...
