Submitting on time

Students with Gmail accounts now have a new temptation to wrestle with. Gmail now allows account holders to set the time that their e-mail is received and to show up chronologically within the recipient's e-mail box. Because of the potential for misuse, each user is only allowed 10 of these time-shifted e-mails per year. Gmail's acknowledgement that the feature could be misused raises an interesting question: what would an appropriate, honest use be? It seems like the feature is useful only to gaslight someone.
