Have the ability to create notifications in advance and schedule a time for them to be sent

Pardon my ignorance and the question posed. Would this be used for staff as well as students? I can see this being used by HR and Marketing departments for various campaigns.
Our students also have asked for the ability to set an alarm / reminder for their lecture X minutes before the lecture is due. Similar to calendar notifications when creating an event in a calendar.
