I talk to a lot of web devs who say they want to know not only the

spec doesn't have any notion of this, but I'd like to do an experimental

actually is in the real world vs. "if only I could..."
Why do they want to know this, and why does dividing currentTime by the
framerate not work?
framerate is not a constant. ;-)
Applications (especially realtime) will want to show the "current"
framerate (for some definition of current - last second, etc). They may
want to take actions based on it as well.
Other apps use frame arrival as a way to know if a connection is still
working (they can also use the currenttime, though).
