Sorting menu by Published Date

[rab]

Got another problem, ive created a menu function from get_navigation() to return any page that is not set as belong to the menu, however i cant get them to sort in the correct order.

Does anyone know what code or variable i would need to change in the get_navigation() function to facilitate sorting be the date the page was published?

Ive messed around with the code to the limit of my ability now with no joy.

Thanks!
