Your original scenario had an external action, instructor login. The
daily increment is the days since account creation.
Since we don't have triggers based on login, you maybe could tickle a
function from your front-end that would simply look for students with
account age > 30 and not paid whenever the instructor logs in.
Short of that, an OS based scheduler (AT, cron, etc.) is your only
choice I can think of
