OK. Your last link could be a movie in itself. I think I would opt for neither and play roe sham bo for the entire hour. Also the f or f question works for a clone but I don't think your allowed to touch the other you when its time travel.
And you can't kill your time traveling self or you die too. If the previous you dies you never get to the current you. If you kill the future you then your dead in real life. Remember when Michael j fox started to fade away bcz his mom wanted his goodies instead of his dad's. You can't mess with the space time continuum like that.
The only option here is to ride it out until all of the other you'd have climbed into time machines leaving only you. And clean up the dead bodies and busted up faces later.
