DBCC DBINFO showing wrong information
If you restore a database as a new database, the dbi_crdate field is the restore date/time.

Here's how to reproduce it:


Create a new database.
Run DBCC CHECKDB() on it.
Look at DBCC DBINFO() for the creation date and DBCC dates.
Back up the database.
Delete the database.
Restore the database (if you want to get fancy, use a different database name.)
Look at DBCC DBINFO() for the creation date and DBCC dates. The creation date will be the restore time, and the DBCC date will be earlier.
