I am creating a **View** in **Drupal 7** for a particular content type. I want to **add filter to show nodes which are updated**. When I am adding Node Update Date field, it is asking for operator and Value to compare with. But I can not provide Updated date of each node. Then I also tried **hook_views_query_alter** to alter the query. When I am adding Query Value to node.created field it take it as a string or you can say Value. Can someone help me to achieve this?
