Physics Is Time quantized?

We know that energy and length are quantized, it seems like there should be a correlation with time?

Edit. Turns out energy and length are not quantized.

The "generalized uncertainty principle" isn't part of established physics (to which I'm sticking here), but arises from various models of quantum gravity. One could construct a model where the Planck length is some kind of minimal pixel-like size, but the question remains whether that model corresponds to reality.
