You would have had to make database backups. This term "rewind" was flawed for ever being used, because its not a rewind. Its just removing the new database and placing an old one. There is no way to set a date or time period for a said "rewind", since its more based on the last time you've backed up your player database.
Thus, to rewind, you would need to replace the current database with the old "backup". If you've never backed up, then you're screwed. No, its not automatic.
