It was more about the spin axis: timezones are vertically cut on a South/North line, while the earth rotation deviates from there.

I actually couldn't find how much it deviates. I assume there's variation depending on the seasons as well.

Not really, there’s a tiny bit of wobble but it moves over a thousands years or so, nothing to worry about. The axis doesn't change to my knowledge.

Magnetic poles changing is not relevant it seems.

Thanks, that I didn't know.

I'm kinda glad I tried to explain this, because I realize just how much I lack the proper words for it.

The earth rotation wobbles a bit, but the axis itself is also not tilted towards the sun (it has no specific reason to) nor tilted towards the inside of the revolution axis relative to the sun.

Basically the earth can be spinning on itself around any axis (let's call it A), while revolving around the sun on an unrelated axis (B). And neither A nor B has to be following the North/South axis. That's where the idea that a latitudinal timezone sees a similar solar cycle seems at odds to me.

If an image can help more, the earth's self rotation and sun revolution in this video are clearly not aligned, nor any of them follow the North/South axis: https://www.britannica.com/video/151528/Earth-rotation-axis-...

Right they aren’t aligned. Sun’s axis is aligned perpendicular to the ecliptic. Earth is tilted 23.5 degrees from that. So North pole is tilted towards the sun on June 21 and South pole tilted towards it on December 21—why there are seasons. Doesn’t affect timezones to my knowledge.
