If time exists then all that has happened and will happened has existence. Does this existence have energy when you factor out time? Do we need infinite energy

If time exists then all that has happened and will happened has existence. Does this existence have energy when you factor out time? Do we need infinite energy to describe a model universe? If there are bounds to this 'non-inertial entropy' then perhaps QM can be explained as quantization noise in 4D spacetime. In this model there are a lot fewer candidate universes.
