For some reason the sorting by Time is being ignored. I tried the solution here (https://forum.getkirby.com/t/kirby-gets-the-date-right-but-not-the-time/1553/4), but nothing seems to have changed. Any thoughts?
adding 'timefield' => 'time', to the plugin’s feed.php file, and changing the <pubDate>… to:
<pubDate><?php echo $datefield == 'modified' ? $item->modified('D, d M Y') : $item->date('D, d M Y', $datefield) ?> <?php echo $timefield == 'modified' ? $item->modified('H:i:s O') : $item->time('H:i:s O', $timefield) ?></pubDate>
