First of all, it's not intended to be a philosophical question, but rather a physical one. So, what can we say about time? Maybe, it's a human way of measuring how things evolve in space? Suppose there are a room with objects within it, where nothing ever happens. There's no need to talk about time, because things don't evolve. Now if YOU, or whatever real physical object is inside that room, it probably would be convinient to you to talk about time. Note that I'm not trying to restrict what time is in the above, just wondering if this could be accepted as a way of defining what time is. Is there anything wrong with the above argument?
