Hi.

My reply is for eZ4, but i don't think it would be much different in previous versions

you will find it at kernel/classes/ezrssexportitem.php

There you can search for this function

static function fetchNodeList( $rssSources, $objectListFilter )

In that function you'll find

$listParams = array( 'Limit' => $objectListFilter['number_of_objects'],
                                 'SortBy' => array( 'published', false )
                                );

You can change "SortBy" there.

Anyway, this is only a hack. I prefer not to hack ezpublish kernel clasess. Maybe i would do an extensions (Basically copying this classes) and so, you will no have problems if you want to upgrade ez in the future.

Hope it helps.

For this you will have to look at kernel/classes/ezrssexport.php

I suppose you're working with RSS 2.0 and not with RSS 1.0

So, you will have to look for fetchRSS2_0 function

there you will find

unset( $itemPubDate );
            $itemPubDate = $doc->createElement( 'pubDate', gmdate( 'D, d M Y H:i:s', $object->attribute( 'published' ) ) .' GMT' );

$object->attribute('published') is the date "printed" in the rss content.
you can change it to

 $dataMap = $object->dataMap();
  

and get the content of that field.

remember you're working now with php code. you cannot think the thinks you do in templates to get content work the same.
i mean, you'll get nothing in php if you use $dataMap.publish_date...

$dataMap is an array, so, for the fields you will have to ask for $dataMap["field"]

So, your code should be like

$dataMap = $object->dataMap(); // this is an array
$publish_date = $dataMap["publish_date"]->content() // this will result a ezdate object
$timestamp = $publish_date->timeStamp();
//and finally
$itemPubDate = $doc->createElement( 'pubDate', gmdate( 'D, d M Y H:i:s', $timestamp ) .' GMT' );
