Imagine twin A sits on top of Mount Everest. Twin B is in a jet that flys westward at the speed of the rotating earth, so is always directly under the sun, at the same altitude as Mount Everest so there is no gravitational time dilation issue. They wave at each other every day as they pass. They do this for one year, so we have the situation where A has travelled a greater distance than B, with the difference being the circumference of the earth x 365.

After one year, who is younger and how do we reconcile two conflicting opinions? Under normal twin paradox thoughts, I would think that since A has travelled much further, and is the one who has gone "out and back" 365 times, A should be the younger twin. But based on Ron Hatch's paper on time dilation with ICBMs referencing GPS satellites for their positioning, and GPS satellites reference an earth based clock for their adjustment, I would think that B is the younger twin.
