This check raises a flag if an exact timestamp of printing is matched to another submission in the target files. It can be useful in detecting submissions based on another submission.
An example of this situation would be where one student prepares a submission and then circulates it to their classmates. The classmates then modify the original files content, but are basing their work off the original. This is one possible method for detecting an infraction of this nature.

Like many of the other checks, there are a few options which can be used to fine tune the behaviour of it at process time, as well as can be set in the default options in the Preferences section.
