However, they may not be equal if the am/pm - * marker 'a' is left out from the format pattern while the "hour in am/pm" - * pattern symbol is used. This information loss can happen when formatting the - * time in PM. - * - * <p> - * When parsing a date string using the abbreviated year pattern ("y" or "yy"), - * SimpleDateFormat must interpret the abbreviated year - * relative to some century. It does this by adjusting dates to be - * within 80 years before and 20 years after the time the SimpleDateFormat - * instance is created. For example, using a pattern of "MM/dd/yy" and a - * SimpleDateFormat instance created on Jan 1, 1997, the string - * "01/11/12" would be interpreted as Jan 11, 2012 while the string "05/04/64" - * would be interpreted as May 4, 1964. - * During parsing, only strings consisting of exactly two digits, as defined by - * <code>Unicode::isDigit()</code>, will be parsed into the default century. - * Any other numeric string, such as a one digit string, a three or more digit - * string, or a two digit string that isn't all digits (for example, "-1"), is - * interpreted literally. So "01/02/3" or "01/02/003" are parsed (for the - * Gregorian calendar), using the same pattern, as Jan 2, 3 AD. Likewise (but - * only in lenient parse mode, the default) "01/02/-3" is parsed as Jan 2, 4 BC. - * - * <p> - * If the year pattern has more than two 'y' characters, the year is - * interpreted literally, regardless of the number of digits. So using the - * pattern "MM/dd/yyyy", "01/11/12" parses to Jan 11, 12 A.D. - * - * <p> - * When numeric fields abut one another directly, with no intervening delimiter - * characters, they constitute a run of abutting numeric fields. Such runs are - * parsed specially. For example, the format "HHmmss" parses the input text - * "123456" to 12:34:56, parses the input text "12345" to 1:23:45, and fails to - * parse "1234". In other words, the leftmost field of the run is flexible, - * while the others keep a fixed width. If the parse fails anywhere in the run, - * then the leftmost field is shortened by one character, and the entire run is - * parsed again. This is repeated until either the parse succeeds or the - * leftmost field is one character in length. If the parse still fails at that - * point, the parse of the run fails. - * - * <P> - * For time zones that have no names, SimpleDateFormat uses strings GMT+hours:minutes or - * GMT-hours:minutes. - * <P> - * The calendar defines what is the first day of the week, the first week of the - * year, whether hours are zero based or not (0 vs 12 or 24), and the timezone. - * There is one common number format to handle all the numbers; the digit count - * is handled programmatically according to the pattern. - * - * <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. - */ -class U_I18N_API SimpleDateFormat: public DateFormat { -public: - /** - * Construct a SimpleDateFormat using the default pattern for the default - * locale. - * <P> - * [Note:] Not all locales support SimpleDateFormat; for full generality, - * use the factory methods in the DateFormat class. - * @param status Output param set to success/failure code. - * @stable ICU 2.0 - */ - SimpleDateFormat(UErrorCode& status); - - /** - * Construct a SimpleDateFormat using the given pattern and the default locale. - * The locale is used to obtain the symbols used in formatting (e.g., the - * names of the months), but not to provide the pattern. - * <P> - * [Note:] Not all locales support SimpleDateFormat; for full generality, - * use the factory methods in the DateFormat class. - * @param pattern the pattern for the format. - * @param status Output param set to success/failure code. - * @stable ICU 2.0 - */ - SimpleDateFormat(const UnicodeString& pattern, - UErrorCode& status); - - /** - * Construct a SimpleDateFormat using the given pattern, numbering system override, and the default locale. - * The locale is used to obtain the symbols used in formatting (e.g., the - * names of the months), but not to provide the pattern. - * <P> - * A numbering system override is a string containing either the name of a known numbering system, - * or a set of field and numbering system pairs that specify which fields are to be formattied with - * the alternate numbering system.
