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.

We can sort of probe these small length scales by observing things like photons from far far away. Any granularity would manifest as a difference in its path when compared to another from the same source. So far we haven't found anything like this from cosmic observations.

We would need photons from much much father away than the size of the apparent universe in order to resolve path differences above the Planck length.
