Change Date Format in Calendar prompt

Question

Hi All,
I am on 11.1.1.5 and the calendar prompt on selection of date/typing of date defaults to MM/dd/yyyy but, the requirement is to make it to default to MM/dd/yy. I have made 3 changes to the localedefinitions.xml file (dateSeparator,dateShortFormat,dateOrder) and they look like below
<property name="dateSeparator">/</property> // separator to use between fields in short date formats
<property name="dateShortFormat">MM/dd/yy</property> // default short date format for locale
<property name="dateOrder">mdy</property> // preferred order of date fields for input
But I still dont see a change in the format of the Calendar prompt. Do I need to change something else too?

Answer 1

I checked under the My Account the locale is set to English and I have the following in the file but still when I select in the prompt the date format is MM/dd/yyyy instead of MM/dd/yy
<localeDefinition name="en"> <!-- english base -->
<property name="localeDisplayMessage">kmsgLanguageName_en</property>
<property name="defaultLanguage">en</property>
<property name="characterSetList">locale:en</property>
<property name="listSeparator">,</property>
<property name="decimalSeparator">.</property>
<property name="thousandsSeparator">,</property>
<property name="dateSeparator">/</property>
<property name="timeSeparator">:</property>
<property name="am">AM</property>
<property name="pm">PM</property>
<property name="timeFormat">h:mm:ss tt</property>
<property name="dateShortFormat">MM/dd/yy</property>
<property name="dateLongFormat">dddd, MMMM dd, yyyy</property>
