Earlier or later than a point in time. Example: " After the [State of the Union] speech, information was learned about the forged documents. With the advantage of hindsight, it's known now what was not known by the White House prior to the speech." (Ari Fleischer, July 9, 2003.) Usage note: As the White House later clarified, in October 2002 the CIA had informed Condoleeza Rice and her deputy that the documents, purporting to show Iraq purchasing uranium from Niger, were forged. So in this example, after technically means "three months earlier."
happening at a time subsequent to a reference time; "he apologized subsequently"; "he's going to the store but he'll be back here later"; "it didn't happen until afterward"; "two hours after that"
Something that is after is behind in place, subsequent to in time or order.
