Yes, I'm not worried about an exact DST. The date items are stored with Timestamp Timezone.
Thanks to everybody for your technical tips and help.

Good point --- in fact, that's probably exactly what Hadley wants,
because "date - integer" will yield a date and not a timestamp. The
form involving interval will do odd things when crossing a DST
transition.
