This is not easily scripted as yo need to provide the exact date pattern you want to use.
You can run the following script through your JavaScript console in Acrobat,. You will need to modify the field names and date format as needed to meet your needs.
// define an array of fields to change
var aFields = new Array("Text1", "Text2", "Text3", "Textn");
// define a character string for the date format
var cDateFormat = "dd-mmm-yyyy";
// define a field object to be used for setting the date format
var oField;
// loop through the field names and add the date format
for(i = 0; i < aFields.length; i++) {
// get the field object for i element in aFields
oField = this.getField(aFields[i]);
// set the date format
oField.setAction("Format", AFDate_FormatEx( cDateFormat));
// end loop field names - get next field name for processing
