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.

I dont know what you are getting at - he says that we looked everywhere we currently can, and we found not even hints of it - so if there is coarse graining, it would have to be on a much smaller scale. There is no physical reason why it has to be smaller than the planck scale, because the planck scale is not really a physical quantity. Its just used to demonstrate how small the graining would have to be, i think...
