In that case, the duration of the block is DefaultDuration (if it
exists), completely different.
Is it intended to say that a duration of 0 at this place means that the
block has the default block duration if it exists?
What is the use case for a duration of 0?
(Note: the meaning of the a block duration of 0 is unclear to me, I'll
ask on CELLAR mailing list to clarify that)
