Time is relative. Events near heavy objects appear slower to observers not near heavy objects. An observer in a similar gravitational field as the event (which is implied if the observer and event are in the same place) will see the events at "normal" speed. The separation of event and observer can be mostly in space when observing a relatively close object falling into a black hole, but can also be in both space and time when looking far into the universe (and thus back in time).
