Under the Broker skill it says it takes 1d6 hours to find a buyer but in the trade section it says that finding a buyer takes the same length of time as finding a supplier which is 1d6 days!
I would say it's for different things. The Skill chapter describes a generic example task, the Trade chapter describes a task specifically for speculative cargo.
The rolls for regular cargo must be much faster, since we do several of them in the ~5 days we generally spend in port.
