How to convert a unix timestamp field in views I'm keeping a Unix timestamp in a text field.  In Views, I want to convert it to a readable date.  This is a commerce view, and the field is a custom field of an order.

Can I use hook_field_formatter_view() to use as my own formatter?  Something like:

function mymod_field_formatter_view($entity_type, $entity, $field, $instance, $langcode, $items, $display) {

    if ($entity_type == 'commerce_order') {
          // figure out field type and instance
    }


}

If that is a way to do it, I want to look at the params through Devel, so what can I return until I'm ready to operate on them?
You can use hook_views_pre_render to change the output of your field..


  This hook is called right before the render process. The query has
  been executed, and the pre_render() phase has already happened for
  handlers, so all data should be available.
  
  Adding output to the view can be accomplished by placing text on
  $view->attachment_before and $view->attachment_after. Altering the
  content can be achieved by editing the items of $view->result.


function MYMODULE_views_pre_render(&amp;$view) {

   if ($view-&gt;name=='viewyouarelookingfor') {

      // do whatever you want

   }

 }
