-/**
- * DateFormat is an abstract class for a family of classes that convert dates and
- * times from their internal representations to textual form and back again in a
- * language-independent manner. Converting from the internal representation (milliseconds
- * since midnight, January 1, 1970) to text is known as "formatting," and converting
- * from text to millis is known as "parsing."  We currently define only one concrete
- * subclass of DateFormat: SimpleDateFormat, which can handle pretty much all normal
- * date formatting and parsing actions.
- * <P>
- * DateFormat helps you to format and parse dates for any locale. Your code can
- * be completely independent of the locale conventions for months, days of the
- * week, or even the calendar format: lunar vs. solar.
- * <P>
- * To format a date for the current Locale, use one of the static factory
- * methods:
- * <pre>
- * \code
- *      DateFormat* dfmt = DateFormat::createDateInstance();
- *      UDate myDate = Calendar::getNow();
- *      UnicodeString myString;
- *      myString = dfmt->format( myDate, myString );
- * \endcode
- * </pre>
- * If you are formatting multiple numbers, it is more efficient to get the
- * format and use it multiple times so that the system doesn't have to fetch the
- * information about the local language and country conventions multiple times.
- * <pre>
- * \code
- *      DateFormat* df = DateFormat::createDateInstance();
- *      UnicodeString myString;
- *      UDate myDateArr[] = { 0.0, 100000000.0, 2000000000.0 }; // test values
- *      for (int32_t i = 0; i < 3; ++i) {
- *          myString.remove();
- *          cout << df->format( myDateArr[i], myString ) << endl;
- *      }
- * \endcode
- * </pre>
- * To get specific fields of a date, you can use UFieldPosition to
- * get specific fields.
- * <pre>
- * \code
- *      DateFormat* dfmt = DateFormat::createDateInstance();
- *      FieldPosition pos(DateFormat::YEAR_FIELD);
- *      UnicodeString myString;
- *      myString = dfmt->format( myDate, myString );
- *      cout << myString << endl;
- *      cout << pos.getBeginIndex() << "," << pos. getEndIndex() << endl;
- * \endcode
- * </pre>
- * To format a date for a different Locale, specify it in the call to
- * createDateInstance().
- * <pre>
- * \code
- *       DateFormat* df =
- *           DateFormat::createDateInstance( DateFormat::SHORT, Locale::getFrance());
- * \endcode
- * </pre>
- * You can use a DateFormat to parse also.
- * <pre>
- * \code
- *       UErrorCode status = U_ZERO_ERROR;
- *       UDate myDate = df->parse(myString, status);
- * \endcode
- * </pre>
- * Use createDateInstance() to produce the normal date format for that country.
- * There are other static factory methods available. Use createTimeInstance()
- * to produce the normal time format for that country. Use createDateTimeInstance()
- * to produce a DateFormat that formats both date and time. You can pass in
- * different options to these factory methods to control the length of the
- * result; from SHORT to MEDIUM to LONG to FULL. The exact result depends on the
- * locale, but generally:
- * <ul type=round>
- *   <li>   SHORT is completely numeric, such as 12/13/52 or 3:30pm
- *   <li>   MEDIUM is longer, such as Jan 12, 1952
- *   <li>   LONG is longer, such as January 12, 1952 or 3:30:32pm
- *   <li>   FULL is pretty completely specified, such as
- *          Tuesday, April 12, 1952 AD or 3:30:42pm PST.
- * </ul>
- * You can also set the time zone on the format if you wish. If you want even
- * more control over the format or parsing, (or want to give your users more
- * control), you can try casting the DateFormat you get from the factory methods
- * to a SimpleDateFormat. This will work for the majority of countries; just
- * remember to chck getDynamicClassID() before carrying out the cast.
- * <P>
- * You can also use forms of the parse and format methods with ParsePosition and
- * FieldPosition to allow you to
- * <ul type=round>
- *   <li>   Progressively parse through pieces of a string.
- *   <li>   Align any particular field, or find out where it is for selection
- *          on the screen.
- * </ul>
- *
- * <p><em>User subclasses are not supported.</em> While clients may write
- * subclasses, such code will not necessarily work and will not be
- * guaranteed to work stably from release to release.
