Hello. Try this:

Sorry - it did not worked - still shows EU date format.

i think the issue is on this blog.php file 

the php echo is "timestamp" but NOT being formatted correctly:

<?php
$blog = new imBlog();
$i = 0;
$posts = array_values($blog->getPosts());
while ($i < 5 && $i < count($posts)) {
echo '<div class="post">';
echo '<a href="#" data-link="index.php?id=' . $posts[$i]['id'] . '" class="post_title">' . $posts[$i]['title'] . '</a>';
echo '<div class="post_body">' . $posts[$i]['summary'] . '</div>';
echo '<div class="post_data">Published by ' . $posts[$i]['author'] . ' - ' . $posts[$i]['timestamp'] . '</div>';
echo '</div>';
$i++;
}
?>

I sent a notification about your question to the company employees, expect an answer from them here in the comments.

Hello Luis

Can I please ask you to show here how you modified the field that Aleksej advised? This way, I can make sure that it was edited in the correct way

I remain available here

Stefano

I tried the following:

[D] [MM] [dd] [yyyy]

and

[D] [M] [d] [yyyy]

None works.

It doesn't work for me either, I got it with...

[D] [M] [dd] [yyyy]

... tested, but the date in the blog does not change. Is there any trick?

1) Press the CTRL key and without releasing it, click on the preview. If the date has changed, then go to #2.
2) Remove all site files from hosting.
3) Re-upload the site completely to the hosting. And not just changes.
4) Clear your browser cache.

Tried it - nothing , same issue, it doesnt change the date format.

It is most likely a bug - the programmers have not made the date-formatting in the blog be tied to the settings.

Hello everyone

I can confirm that at the moment, those specific dates are not changed based on the setting you mentioned and in fact, cannot be changed at all

I've informed the developers of this so that an improvement can be made to the software in order to make these dates configurable as well

Thank you for your feedback

Stefano
