Time in theoretical physics (in all geometries) is NOT considered as a dimension, but as a COORDINATE. (That is why i symbol (imaginary) in front of it when for mathematical simplicity it is unified with space coordinates). A dimension in physics mean "degree of freedom to MOVE in". So, without defining what does motion in time (or in energy, or in mass) mean there is no sense in calling time a dimension.

In popular literature word "coordinate" sometimes aberrated into "dimension".

There is a trend now to actually remove time from physics as a non-existing in reality entity, because all attempts to fill it with "physical" meaning failed.

By time we simply mean rate of periodic electromagnetic processes (oscillations) in different reference systems.
