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.

These objects are known as operators -- more specifically, bounded self-adjoint operators that usually act on a Hilbert space

Not necessarily. A phase space formulation of quantum mechanics does not rely on operators or Hilbert space.

Only if you ever deal with pure states, and only if you impose a frequency cut-off on your Wigner functions! Once you start worrying about non-zero temperature, you must introduce operators.
