Is it possible to play skin animation in reverse? [Three.js]

Question

How would I go about playing an animation backwards?

I've tried giving the animation handler negative delta but that just stops it. Subtracting the delta from this.currentTime of the animation doesn't work either.

Any ideas?

Since Three.js r69 it's possible to play animations in reverse order by setting animation.timeScale = -1 though only when animation.loop = true.

See Reverse animation, feature request #5062 for more updates.
