Daylight saving time rules can change... Just because you stored it correctly now doesn't mean it is correct in the future (when it's needed).

  Sure but that is a separate issue - in that case you didn't 'forget' about it

    But it's not an issue to begin with if you just store it in the correct local time zone.

      I am not advocating anything other than that

    Timezone dbs lag, so do not solve every problem.
