Hello,
Welcome to our community!
There is no built in way to schedule jobs like this right now.
Note that you can schedule recurring jobs[1], but it follows the cron model (i.e. run at X time). There is no way to make X variable in that case.
In order to achieve something like this you would need to use the API and external scheduling system to make the call at the desired time.
