There's an intuitively obvious use of "real time" in cinematography which
may be helpful here. Back in the early days the cameras were hand cranked:
slow motion was achieved by "over-cranking," fast motion by "under-cranking."
When a movie is "not too slow" and "not too fast" it is in "real time." 
(ie., when there exists a temporal correspondence between recording and
playback).
