AM / PM is not uppercase when using I18n.l with% p in Rails

I have a problem that I cannot understand. I am trying to format the date using a custom format that I defined in my en.yml file:

en:
  hello: "Hello world"
  time:
      formats:
          history_table: "%m/%d/%Y %I:%M:%S %p %Z"

This is called with the help of the 'l' helper:

l version.created_at, :format => :history_table

For some reason, this displays AM / PM in lowercase rather than upper case, as it should be with% p.

I played a little in the console, and it looks like this is the difference in behavior between the localization function and strftime:

ruby-1.9.2-p180 :043 > I18n.l user.updated_at, :format => "%m/%d/%Y %I:%M:%S %p %Z"
 => "03/23/2011 01:52:16 am UTC" 
ruby-1.9.2-p180 :044 > user.updated_at.strftime("%m/%d/%Y %I:%M:%S %p %Z")
 => "03/23/2011 01:52:16 AM UTC"

Am I doing something wrong? This is mistake? Any guidance is greatly appreciated because my forehead hurts from hitting it against the wall.
