Under 10.6, fans in the Dock have the ability to be sorted by "Date added". This is extremely useful, but... I have a custom doc icon that makes the folder look nicer (I'm sure you've seen them). In order to keep them on top of the stack, you set the creation date to far in the future (2020). But if I use "Date added" instead of "Date created", they don't sort correctly. So, what is the "date added", and is there a way to set it using Terminal?
