Probable-lie "control" questions are similar in both screening and specific incident polygraph examinations. However, in the latter case, they are generally worded in such a manner as to exclude from their scope the incident under investigation. "Time bars" are frequently used to accomplish this.

On p. 116 of A Tremor in the Blood: Uses and Abuses of the Lie Detector, (2nd ed.), David T. Lykken provides an example of a CQT administered by David Raskin to a defendant accused of stabbing a man to death. You'll note that the probable-lie "control" questions here all include time bars:
