Let's assume there are no side effects of spinning at C. Looking at the top side of the hole, time would speed up in the direction of spin and slow in the opposite direction. The other side of the doughnut would be exactly opposite giving the doughnut a sort of north and south temporal pole. Does that sound like a reasonable analysis? Help me out here, I have a feeling this is much deeper than I think.

You cannot ignore the side effects only bodies with extreme gravity like neutron stars and black holes can rotate at speeds anywhere approaching the velocity of light because the centrifugal forces would immediately disrupt them.  The bodies currently being described with earth like masses and densities cannot cause significant time dilation.  Also earth size and density objects cannot be anything other than spheroids (i think ) because the strengths of rigid materials are totally inadequate to resist the gravitational forces involved in creating a solid state so far from equilibrium.  It might just be possible to produce a large stable doughnut shape under gravity if the body was a fluid and rotating both on its axis and round the circular axis of the doughnut like a smoke ring.

Soul, it's a thought experiment. Pretend I have this super material that can handle the forces even at 99.9% of C.

That is not a sensible thought experiment because it will always lead you to a useless fact it is far better to consider a highly dense fluid structure that is rotating so fast.  this will lead you towards concepts that i have already described in the new theories area.

Could you step back a little and say why you are interested in this concept.

farsight once suggested the electron is a torus (doughnut). I must at least consider the possibility he is right. If it were as he suggests then it would be a wave in the shape of a torus and that wave would create a field, somewhat akin to a gravitational field, except it would be a field made of changing time dilation. The problem, how can that field appear to us as a negative electric field?

It is much easier for me to consider time dilation caused by motion to be the experience of material in motion and not an actual change in the passage of time. Material in motion experiences time dilation because its atoms must complete the patterns they experience over a greater distance. The innermost constituents of the atoms all move at the invariable speed of light, so any movement must cause the patterns to repeat over a greater distance. The greater distance requires more time, since the speed of the inner most constituents is invariable.

So material in motion experiences time as dilated. It is not time that is changed. It is the material in motion that is changed.

We knew this somewhere around two hundred years ago. For some reason, unknown to me, we now choose to deceive our students instead of teaching them the reality of it.

I know that light is affected by a gravity and I suspect mass is affected by light. That affect would be so minor as to be undetectable by our instrumentation. If that were the case then it is possible we confuse the field of an electron with a field of time dilation.
