code: private static String tempDateStringForJodaTime(String dateString) {
          final String fromPrefix = "292278994-";
          final String toPrefix   = "292278993-";
          return dateString.startsWith(fromPrefix)
               ? toPrefix + dateString.substring(fromPrefix.length())
               : dateString;
      }
docs: Returns a date string with the prefix temporarily substituted, if
  applicable, so that JodaTime can handle it.  Otherwise, if not applicable,
  the original date string is returned.
