Well, time doesn't have so much to do with it as temperature and pressure 
do, as I understand it.  But then again, it takes time to take a piece of 
glass, put it in a subducting plate, and mash it back into the mantle.

Well, I'm not overly sure about the window thing, but I can say with 
certainly that glass is an >extremely< viscous substance.  Not likely to see 
it flow on its own in our lifetime.

And for the record, I like dinosaurs.
