24-hour duration (and 12-hour duration as well) for buildings where you must collect something results in the collection moving further and further in time. If you start collecting something (e.g. Genie) at 9 a.m. next day it's maybe at 9.30 a.m because you couldn't do it at 9, next day it's 10 a.m. etc. and after a week or two you have actually lost one collection.
If you change it to 23 hours (and the 12-hour collection to 11.5) this will not happen and you will be able to collect everything every day
