I included some time travel stuff in my UPS game (Universal Pizza Service, a spin-off of Ben Burns' Zeta Complex) at last year's NTRPG. But it was really just time going faster or slower as PCs jumped between dimensions. The objective was humor (as in Stanislaw Lem).

That’s a great idea. I’m heading to Yellowstone to photograph wolves at the end of the month and those will be very welcome.
