24 hourdate format Datefield.

Hi
I am using datefield component in vaadin. i want 24 hourformat in datefield(Means remove am and pm) from datefiled.
i am able to achieve this one by using changing locale to UK.

 DateField df = new DateField("Date");
       df.setResolution(Resolution.MINUTE);
      df.setLocale(Locale.ENGLISH);

but i want to 24 hour format where locale should be Locale.ENGLISH . and without changing the locale.UK.

please help me

Thanks

Have you tried to create your own locale? 

bLocale = new Locale("en", "US");
 

Alternative:
I use DateField.setDateFormat()  because I do not want to bring locale into the picture as there's actually no locale that does what I want.
