The database updates every week, not Sentinel. (I realize that is what you meant, but just to eliminate confusion because Sentinel updates too, as well as the database.)
I sometimes wonder if they forget to update that database version date.
For some reason Sentinel knows to download it as an updated database, even though the date indicates it's not updated.
