How do I format my created_at output correctly with I18n?

I am calling it in my view like this:

<td class="center"><%= l o.created_at %></td>

This is being outputted like this:

Mon, 22 May 2013 04:04:43 +0000

For starters, why is it displaying May 22, 2013 and not April 22?

When I do it in the console, I get this:

> o.created_at
 => Mon, 22 Apr 2013 04:04:43 UTC +00:00

I don't want it to display the time, or rather would prefer to just say something like:

Monday, April 22, 2013 @ 4:04am

How do I do that?

Solution

You can add custom date/time formats to your translation file. To see what time-based substitutions are possible, consult a reference for strfime

formats:
  default: ! '%Y-%m-%d'
  long: ! '%B %d, %Y'
  short: ! '%b %d'
  custom: ! '%A, %M %B, %Y @ %l:%M%P'

In your view, you'd make use as follows:

<%= l o.created_at, :format => :custom %>

You may need to get rid of blank entries in your en.yml file to correct your translation errors.
