We have a client here in the UK using RSS feeds, and they have also noticed that the RSS Feed pubdate is in incorrect format - if you try and validate the feed using (for example) the W3C rss feed validator, it complains:

line 20, column 44: pubDate must be an RFC-822 date-time: Tue, 16 Sep 2008 09:23:22 BST

The help attached to it states:

Message

element must be an RFC-822 date-time
Explanation

Invalid date-time. The value specified must meet the Date and Time specifications as defined by RFC822, with the exception that the year should be expressed as four digits.
Solution

Change the date-time format to comply with RFC822. Here are examples of valid RFC822 date-times:

<pubDate>Wed, 02 Oct 2002 08:00:00 EST</pubDate>

<pubDate>Wed, 02 Oct 2002 13:00:00 GMT</pubDate>

<pubDate>Wed, 02 Oct 2002 15:00:00 +0200</pubDate>

Common errors include localizing the month name or the days of the week, not using the exact abbreviation provided by the specification, or attempting to use a time zone name that is not listed. See Section 5.1 for the list of allowable values for these portions of the date.

Here is an example of an invalid RFC822 date-time. This is commonly seen in RSS 1.0 feeds generated by older versions of Movable Type:

<pubDate>2002-10-02T08:00:00-05:00</pubDate>

So presumably it does not like the BST?

This is fairly urgent.

Donsheng, when you need a little break from repositories, can you fix these dates?

Look for the rss_add_items() function in lib/rsslib.php ... this line explicitly sets the date that way:

$result .= rss_full_tag('pubDate',3,false,date('D, d M Y H:i:s T',$item->pubdate));

Thanks - I'll grab a copy of the relevant script from the public CVS - how long does it take for your changes to get across to there?

Sean K

http://tracker.moodle.org/browse/MDL-12563?page=com.atlassian.jira.plugin.system.issuetabpanels:cvs-tabpanel

And it'll be in tomorrow's weekly builds.

And it's probably in CVS mirrors by now too.

Client has just reported that now their feeds are broken:

http://www.jbevirtualtraining.co.uk/dev3d/rss/file.php/4/2/data/1/rss.xml

shows the following:

JBE Virtual Training http://www.jbevirtualtraining.co.uk/dev3d <div style="text-align: center;"><font size="2">This is a new Moodle site for JBE Virtual Training<br /><font size="1">Running Moodle version 1.9.2</font></font><br /> </div> Moodle © 2008 JBE Virtual Training http://www.jbevirtualtraining.co.uk/dev3d/theme/chameleon-jbe/pix/i/rsssitelogo.gif moodle http://www.jbevirtualtraining.co.uk/dev3d 140 35 RSS Error http://www.jbevirtualtraining.co.uk/dev3d Wed, 17 Sep 2008 08:30:49 GMT Error reading RSS data http://www.jbevirtualtraining.co.uk/dev3d

Also, neither of their sites (live or dev) have an rss directory under dataroot.

Cron is set to run every 15 minutes on both of their sites.

It is definitely running

Any ideas?

Sean K

I'm pretty sure it's not related to the change I made.

And now, when I check that feed, it looks OK to me - no errors.

Why would running it manually be different to running it scheduled?

cheers

$result .= rss_full_tag('pubDate',3,false,date('D, d M Y H:i:s T',$item->pubdate));

becomes

$result .= rss_full_tag('pubDate',3,false,date('D, d M Y H:i:s O',$item->pubdate));

The "O" in date() will give you +0000 for GMT, -0500 for EST, etc.
