Hi all, I have a custom list definition and I need to include a calculated column Days open in it which says that the number of hours /Days elapsed after the item has been created. I am trying to use predefined column Created to get the date created and I am in a confused state of how to include the today date functionality and get the difference in terms of Days /Hours.Can some body guide me on how to implement this in my list definition .I need to achieve this by using pure XML but not by any coding. Thanks,
