Does time move L->R, R->L, or Both?

I just watched one of the smartest science videos I’ve ever seen (and I watch a lot of science videos!). I’ll paste it, with a comment beneath.

They’ve accurately depicted that the time gradient makes the squirrel’s head “top-heavy” and therefore it spins to the right (sinks). But wouldn’t the same gradient make the squirrel’s feet “bottom-light” and spin to the left, i.e. rise?

We think of time as only moving from left to right. But certain languages (e.g. Hebrew), and indigenous traditions (e.g. the Aymara*) suggest that time also moves from right to left.

That’d mean some of the particles, at the bottom-most layer, would not just appear to be slower, but would actually appear to be moving in the opposite direction. Perhaps there’s not just time dilation, there’s also time contraction.

*The Aymara speakers of the Andes consider the past to be in front of them and the future behind them.
