How long the sell listing will showup after submit?

when you post and auction there is a little disclaimer at the bottom that says that it maybe take quite a while for your auction to show up. I've heard folks say it took over 8 hours for theirs to show.
My non-designer goods show up within seconds to minutes of my posting, but I do notice that designer goods take awhile to show up. Maybe they're scrutinizing it more since they're designer? :shrugs:
