"At this point in time" means "
now."
Before the Watergate scandal, nobody said "at this point in time" much. In the early 1970's, however, John Dean, lawyer and advisor to U.S. president Richard M. Nixon, used the phrase repeatedly in his testimony to Congress during the Watergate hearings. "At this point in time" was a smash hit among the millions of viewers of those hearings, a linguistic meme that became commonplace overnight. While its popularity has waxed and waned since its initial outbreak, "at this point in time" is still, at this point in time, going strong.
Since it is a goofy way to say something simple, using "at this point in time" when you mean "now" is generally considered bad style by those who care about good English usage.
