We customize the way that date(create and publish) displays on article details page(com_content) . If you want to show in this format “September 9, 2011“, this way will help you to do that
Open templates/ja_magz/html/com_content/article/default.php file
from
<?php if ($params->get('show_publish_date')) : ?>
<dd class="published">
<span><?php echo MagzHelper::relTime($this->item->publish_up); ?></span>
</dd>
<?php endif; ?>
<?php if ($params->get('show_create_date')) : ?>
<dd class="create">
<span><?php echo MagzHelper::relTime($this->item->created); ?></span>
</dd>
<?php endif; ?>
Change to
<?php if ($params->get('show_publish_date')) : ?>
<dd class="published">
<span><?php echo JText::sprintf('COM_CONTENT_CREATED_DATE_ON', JHtml::_('date', $this->item->created, JText::_('DATE_FORMAT_LC3'))); ?></span>
</dd>
<?php endif; ?>
<?php if ($params->get('show_create_date')) : ?>
<dd class="create">
<span><?php echo JText::sprintf('COM_CONTENT_CREATED_DATE_ON', JHtml::_('date', $this->item->created, JText::_('DATE_FORMAT_LC3'))); ?></span>
</dd>
<?php endif; ?>
and you can see format date in language/en-GB/en-GB.ini file
Line 228:
DATE_FORMAT_LC3="d F Y"
