Apart from the language issue,
I’d like to convert the dates to human-readable format
I have used this code to make this change site wide, it works in all posts and pages but not for the search results
// Convert all dates to human-readable format
function custom_time_ago() {
return human_time_diff(get_the_time('U'), current_time('timestamp')) . ' fa';
}
add_filter('the_time', 'custom_time_ago');
add_filter('get_the_date', 'custom_time_ago');
add_filter('the_modified_time', 'custom_time_ago');
