 I am using the en_US Tor Browser 3.6.5 on Linux, with the system set to a
 non-English locale.

 When I visit [http://browserspy.dk/date.php], the time is displayed as
 UTC, but the "Locale String"/"Time on your PC" tests show the time in the
 format of the non-English system locale.

 Both of these tests print the value of the JavaScript
 Date.toLocaleString() method.

 I can control the format used by toLocaleString() by explicitly setting
 the LANG environment variable when running start-tor-browser.
