If you’ve enabled automatic backups, RDS allows you to create a copy of your database at its state at a particular point in time, allowing you to recover from catastrophic problems. This functionality exposes a Latest Restorable Time, which is the latest point in time you create the copy from. RDS usually keeps this value within 5 minutes of the current time, but if it falls behind, you will have to contact AWS support to have the problem looked into.
