title: Redefine a Locale’s date-time format, on the JVM level
body: <p>We have a system that displays the Dates based on the Locale chosen by the user. A customer is requesting to have the date format of a locale to be similar to the en_US format.
  The problem is that it is not possible to perform code changes.</p>
  
  <p>Is there a way to change the date format for a Timezone on the JVM level? Maybe something similar to the <a href="http://www.iana.org/time-zones" rel="nofollow noreferrer">IANA timzezone change TZUpdater</a>?</p>
  
  <p>Thank you.</p>
  
  <p><strong>Edit: This is not a duplicate and the links in the comments are not similar. I don't want to set the default Local, I want to map the Date Format for the New Zealand English dates  to be similar to the Date Format for the Untied States English date Format.</strong></p>
