On themes/Frontend/Bare/frontend/blog/box.tpl you have the follow block:
{* Date *}
{block name='frontend_blog_col_meta_data_date'}
{if $sArticle.displayDate}
{$sArticle.displayDate|date:"DATETIME_SHORT"}
{/if}
{/block}
In our case we want to show date in a different format like:
{$sArticle.displayDate|date_format:"%d %B %Y"}
The problem is the output doesn’t take in account the selected shop localization for month translation. It always show us “28 June 2016”. In a german shop it would show us “28 Juni 2016”, but no.
