Adaptive Release based on number of hours after submission

How about a time-based Adaptive Release setting, rather than a specific date? For example, once a student submits an assessment, new content will appear 24 hours later. We have a request from our Writing Center to release modules at a slower pace, but not on a specific date. They would like to release new modules 24/48 hours after students complete the first. Although we can probably "design" our way out of this, it is an interesting idea that might help slow the course pacing while allowing students to somewhat work at their own speed.
