Use syndicate rss to export modified datetime ?

Wednesday 10 May 2006 3:00:09 am

Hello,

I want to do a rss export form a 1st site and an rss import in the second site to share content between 2 sites.

With the standard rss module, when an object has already been imported, there is no update when content change.

I want to update the imported content if modified.
To do so, i want to export the modified datetime of the content in the rss feed,
and then in rssimport.php, test if existing object modified date is different from the modified date of the object from rss feed and update the content in this case.

I have installed the extension syndicate rss, but i don't know how to use it deeply.
First, how can I do to export the modified datetime in the rss feed ?
Can syndicate extension help me to do this ?

thanks for help
