On page 122 (Simply Rails 2), when I run: script/generate model Story name:string link:string, it creates all of the necessarry files, but, instead of it creating: db/migrate/001_create_stories.rb, it creates: db/migrate/20090522522_create_stories.rb

As you can see, it is using the date instead of "001". is this just standard in the latest rails, or is there something wrong?
