Add Duration field to sort criteria programatically?

Question

Can someone please tell me how to add duration(CCK field) to sort criteria of views programmatically because it is not listed there by default?

Answer 1

If no handler/field is provided in Views you have to refer to the API and write the views plugins to enable what you want to sort by.
