docs: Returns the number of elapsed seconds since the last recorded vsync event. This 
          will come from a vsync timer event in the timer if possible or from the application-reported
            time if that is not available. If no vsync times are available the function will 
            return zero for vsync time and frame counter and return false from the method.
