A Point in Time?

It grates like fingernails on a blackboard every time I hear someone use that term to indicate now, or some event. Time isn't a physical entity, it is an arbitrary reference to physical events that happened to a later happening. The term sounds Einsteinian perhaps but instead of showing mental ability it just shows just how dumb they are. Its like the term "where is it at?"--fortunately I unlearned the term when a friend kept saying "its behind the at". Perhaps the "point of time" is on the end of their nose? Time can't be pointed to. It does not have a position in space. Its reference can only be used by reference between one event and another; such as tick to toc. Or the moment you fell in a lake when you were 16 years 30 days 10 hours 5 minutes 23 seconds old. Even defining it that close leaves split seconds open to finding a point. So when someone voices the phrase "at this point in time" or similar have them define the point "exactly".
