The directionality of time is a characteristic that is different than spatial dimensions but it is not the defining characteristic. Simply making time non-directional does not transmute it into a spatial dimension. The thing that differentiates time from the spatial dimensions is that time is a temporal dimension not a spatial dimension, irrespective of its directionality.
