And I don't want to expand on it, because otherwise this thread goes
completely elsewhere again and I want to keep the focus on this patch.
These are two different problems, which have have only in common that it's
about rounding of time.

You have a weird definition of "regression", since when is a bug fix a
regression? We can discuss whether it's the correct fix and I described
earlier in this thread the basic problem, which the current 2.6 behaviour
fixes. I'd really prefer if we could based on that discuss a proper fix,
instead of just falling back to the wrong 2.4 behaviour.
