title: toLocaleDateString not working properly in Chrome
body: <p>I have two machines (on different development networks). On one machine if I manually set the language on Google Chrome to English UK, date format is correctly displayed as DD/MM/YYYY if I run the following within the Chrome developer tools console:</p>
  
  <p>(new date()).toLocaleDateString()</p>
  
  <p>On a separate network where I am managing the locale via GPO, the setting is correctly configured and the language is displayed in English UK, but if I run the above command the date is displayed as YYYY-MM-DD.</p>
  
  <p>On each network my timezone is UTC+00:00. I cannot see any configurable difference - simply that one is manual and one is GPO. </p>
  
  <p>The material online about this (including on StackOverflow) all seems to indicate that this should be working.</p>
