It would be the same day between 23:00 and midnight, even if the
day itself is a DST-switch-day.

The other question: what that would be "one day minus one hour" after
a timestamp between 3am and 4am of the saturday before Spring DST day?
Answer: I don't care. That would be a weekend, and I happen not to care
about weekends for my task ;-)
It's just not specified. If a solution works for all other cases, it'll
be fine for the spec, even if it gave me a date in year 42 BCE for that
particular situation. (ditto for Autumn, although I'd personally tend to
prefer the second one of the two "2am-3am" hours then)
