Change date format in comments

Question

How can I change the date format in my comments?

Right now it looks like this:

Sat, 09/01/2012 - 12:00

I want it to look like this:

Saturday, September 1, 2012

I was able to achieve this in page.tpl.php in a section where I just display the date, but have no idea where to do this so it works for my comments too.

Answer 1

If you want to do it sitewide, you can edit the definitions at admin/config/regional/date-time/formats

You can also add your own formats there, and then use them in format_date() similar to what @Epok outlined.

Answer 2

When you watch your comment.tpl.php you see that you can override some variables with template_preprocess_comment()

I don't know if it's the best way but it works fine for me. You have to put this function in template.php

function mytheme_preprocess_comment(&$variables){
  $variables['created'] = date('l, F d, Y', $variables['elements']['#comment']->created);
  $variables['changed'] = date('l, F d, Y', $variables['elements']['#comment']->created);
}

There is a post about this on Drupal.org

Answer 3

You can also use format_date() function: format_date($timestamp, $type = 'medium', $format = '', $timezone = NULL, $langcode = NULL)

Please note UNIX timestamp is timezone blind.

function YOURTHEME_preprocess_comment(&$variables) {      
  $variables['created'] = format_date($variables['elements']['#comment']->created, 'custom', 'l, j F Y h:i A');
}
