Crew Scheduling would have to place the assignment on your schedule 9 hours prior to you going on call, which in this case would be no later than 17:16 on the 30th. (When your on-call day begins at midnight, the cutoff is 15:00.) If you checked your schedule after 5:16 pm on the 30th and nothing was there, you would simply go on long call at 2:16 am on the 31st with a 12 hour callout.
