Mathematic and scientific formulas describe and calculate the individual properties of our physical reality. This might create an argument but essentially time is not a definitive substance in and of itself. Rather, time is an effect and the product of tangible physics such as geavity/mass & space. To answer your question, zero seconds is the expression that time quit moving and physical reality is paused. If you were to pause reality and insert an object into reality and then remove that object before pressing play, then yes. But that isn't possible nor does that make sense because that would indicate that there are two tracks of time existing simultaneously and to observe the object existing in the other timeline while under a pause and then seeing the object disappear before time passing resumes would mean that the observer exists in genuine reality and the zero second reality must exist in a false state. Simply stated, pause theory ignored, an object can either exist or not exist but cannot exist in a state of non-existence.
