/**
* 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.
