This has been a long-held wishlist item, really, and I thought I might as well take the opportunity to add the instructions. The double versions of STATE require both the nextthink field and time global to be double (but they're not resolved properly yet: marked with "FIXME double time" comments). Also, the frame number for double time state is integer rather than float.
