-
-- Automatic CreatedAt UpdatedAt (use Hooks instead)
-- Nested eager loading

 #### Supported Databases
 
 - PostgreSQL
 
 Note: Seeking contributors for other database engines.
 
+#### Automatic CreatedAt/UpdatedAt
+
+If your generated SQLBoiler models package can find columns with the
+names `created_at` or `updated_at` it will automatically set them
+to `time.Now()` in your database, and update your object appropriately.
+
+Note: You can set the timezone for this feature by calling `boil.SetLocation()`
