From the New York Times:

A critic’s notebook article on Monday about the prevalence of standing ovations at Broadway shows described incorrectly the quickness with which audience members appeared to be on their feet at a performance of the current revival of “Death of a Salesman.” Their ovation seemed to occur within a millisecond — one-thousandth of a second — not a megasecond, which is one million seconds.

Good thing – some Broadway production runs don’t last that long.
