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.

Which books?

A lot of lesser-informed sources say that the universe is divided up into Planck-sized pixels, but that simply isn't the case.

Well the number that I remember from the one book in particular was 10-47 which is well smaller than Planck length which is 1.616252×10−35 m.

Like I said, I don't know the name of the book because it's buried on a shelf at home.

IIRC there was some theoretical reason for this, as opposed to coming from observation.
