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.
