Useful when you need to store the offset of a specific event in the past where the timezone data doesn't matter. Especially logs since you want to know when it occured, so you store unqualified offset so the DoS attack doesn't suddenly happen an hour earlier than it says in the logs if DST happens between attack and the admin reading the log.
