I see now, that did the trick. My mistake was assuming that $duration->days would give the same result as $duration->delta_days( $start_date ) or $duration->in_units('days').
I'm curious now though, what >is< $duration->days used for, if not for expressing the length in days of a $duration?
I *believe* it is so you can say "X months, Y days and Z hours" or things like that.
