RFB did change the "targeting" on the Attack Map, but I do not remember exactly what they did. Perhaps someone else more familiar with it can comment. but if you are talking about a figure like "2:25" and it is counting down as you have a target locked and it is closing, or counting up as a target is moving away, or similarly if you have shot torpedoes and they are closing, that is what that is. RFB may have removed the additional targeting info as being "not real"...
