Airbnb Check-in/Out Time

I am API connected with Airbnb. I want to set my check-in/out times to 4:30 PM and 9:30 AM. Airbnb will not update with the half hour change. The listing still shows 4:00 check-in and 9:00 check-out.

Unfortunately, Airbnb only allows setting the check-in/out times to full hours. They do not support sending minutes for those check in/out times.
