Indeed there is. I think their approach ends up being circular
  yet still might prove to be practical nonetheless. It's an
  interesting approach. I'll have to work my way through their
  submitted paper though. Thanks for the link: Time has been one
  of those bits of QM that's been tricky: Most of them time, it's
  eliminated from it as much as possible or rather it's used in
  the way that its used in mathematics: as a counting mechanism
  like 1+1=2 rather than something whose origins can be
  investigated and properly quantized further. Thank you! Anything
  having to do with Time is up my alley.
