How long does it take water to freeze at 212 degrees Fahrenheit?

Oh, dude, you're asking about freezing water at 212 degrees Fahrenheit? That's like asking how long it takes to make ice cream in an oven. Water freezes at 32 degrees Fahrenheit, so at 212 degrees Fahrenheit, you're looking at boiling water, not freezing it. So, like, forever, man.
