so in the night where the DST transition takes place, imagine you get
up to go to the toilet because you drank to much coffee the evening
before ... right in the hour where DST transition happens:
isn't there a `date`?
Or the other way round: how many hours do you have to left to sleep
until 8am?

The situation with date sounds like there "is an hour once per year
when no date exists", but this is not true.
