Can time really slow down due to earth revolution?

From The Elseworlds episode 3 (Supergirl season 4 episode 9),
When Evil Superman (Dr. Deegan) regains The Book of destiny and started to rewrite reality (@26:13 min), Flash (Barry Allen) suggested about slowing down the time by running around the globe in opposite direction @just over Mark7 speed. So that it can create centrifugal force that'll slow down earth and everything else.
So my question is, is it really possible to do such thing in reality in given circumstances or is it just another science fiction element for entertainment purposes? Is it scientifically possible or is it just a theory?

To be fair, it worked in Superman. If anything, it should have worked doubly well.

Is it really possible to do such thing in reality
No. It's completely ridiculous.
Physics doesn't work that way, nor does space-time.
Indeed, the speed they mention "Mach 7" is ridiculously slow. Escape velocity (say for Apollo or the Space Shuttle) is Mach 33!
While this is a rather nice tribute to Superman: The Movie and the scene where Superman reverses time by spinning the planet backwards, the physics of what Barry suggests are completely nonsensical within the stated limits. While mass does increase with velocity (per Einstein's theory of special relativity) Mach 7 is nowhere near fast enough for two human bodies to influence a mass the size of the Earth. While gravity has been shown to alter the flow of time (read up on the "Hafele–Keating experiment" for the details) Kara and Barry can't come close to generating that level of power at that low a speed.

Basically, this is a call-back to the Superman where he did exactly the same impossible thing.

If they actually managed to slow down the rotation of the Earth, that would affect solar time (the sun would move across the sky slower, and a full rotation of the earth would take more than the usual ~24 hours). However, the inhabitants of Earth would still be experiencing time at the same rate as usual (so, lots of comments about how this day is "really seeming to drag on forever", and wondering why the sun is still up at 7PM, when it was supposed to set at 5:30). However, if this is a magical thing, it's at least possible that this change would have an effect on a spell.

@RDFozz It's much worse than that. Earth bulges in the middle. The surface is 21km "higher" at the equator than at the poles. Its rotation keeps the Earth's oceans and air "uphill". If the rotation were to slow all that water and air would settle at the poles. We'd have a strip of dry land at the middle latitudes between a polar ocean and a high desert with air too thin to breathe. Loss of the Coriolis effect and the longer days and nights would make weather go crazy. youtube.com/watch?v=tx_pawMRPAY Don't let super heroes geoengineer.

@RDFozz We have willing suspension of disbelief regarding the basic premise of any SF/fantasy. The question is where the fiction ends. Car engines in the Arrowverse seem to obey the normal laws of physics and chemistry (actually, the TV laws -- they still explode in unrealistic ways).

@Barmar - Agreed. Let me know I haven't seen the episode in question yet - that's why I made a passing reference to magic. In magical terms, the elements are earth, air, fire and water, as opposed to hydrogen, helium, etc. I can tell that this does tie into the very super-speed that we're suspending our disbelief about. The show tries to make things at least seem semi-scientific to the average viewer. This may be a case where they tried to make it seem scientifically plausible too hard, generating the opposite effect. Or, we may be too knowledgeable to accept the handwaving.
