* 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. *

* To format a date for the current Locale, use one of the static factory * methods: *

 * \code
 *      DateFormat* dfmt = DateFormat::createDateInstance();
 *      UDate myDate = Calendar::getNow();
 *      UnicodeString myString;
 *      myString = dfmt->format( myDate, myString );
 * \endcode
 * 

 * \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
 * 

 * \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
 * 

 * \code
 *       DateFormat* df =
 *           DateFormat::createDateInstance( DateFormat::SHORT, Locale::getFrance());
 * \endcode
 * 

 * \code
 *       UErrorCode status = U_ZERO_ERROR;
 *       UDate myDate = df->parse(myString, status);
 * \endcode
 * 

*
• SHORT is completely numeric, such as 12/13/52 or 3:30pm *
• MEDIUM is longer, such as Jan 12, 1952 *
• LONG is longer, such as January 12, 1952 or 3:30:32pm *
• FULL is pretty completely specified, such as * Tuesday, April 12, 1952 AD or 3:30:42pm PST. *

* You can also use forms of the parse and format methods with ParsePosition and * FieldPosition to allow you to *

*
• Progressively parse through pieces of a string. *
• Align any particular field, or find out where it is for selection * on the screen. *
