	62	+ * <code>SimpleDateFormat</code> is a concrete class for formatting and
	63	+ * parsing dates in a locale-sensitive manner. It allows for formatting
	64	+ * (date -> text), parsing (text -> date), and normalization.
	65	+ *
	66	+ * <p>
	67	+ * <code>SimpleDateFormat</code> allows you to start by choosing
	68	+ * any user-defined patterns for date-time formatting. However, you
	69	+ * are encouraged to create a date-time formatter with either
	70	+ * <code>getTimeInstance</code>, <code>getDateInstance</code>, or
	71	+ * <code>getDateTimeInstance</code> in <code>DateFormat</code>. Each
	72	+ * of these class methods can return a date/time formatter initialized
	73	+ * with a default format pattern. You may modify the format pattern
	74	+ * using the <code>applyPattern</code> methods as desired.
	75	+ * For more information on using these methods, see
	76	+ * {@link DateFormat}.
	77	+ *
	78	+ * <h4>Date and Time Patterns</h4>
	79	+ * <p>
	80	+ * Date and time formats are specified by <em>date and time pattern</em>
	81	+ * strings.
	82	+ * Within date and time pattern strings, unquoted letters from
	83	+ * <code>'A'</code> to <code>'Z'</code> and from <code>'a'</code> to
	84	+ * <code>'z'</code> are interpreted as pattern letters representing the
	85	+ * components of a date or time string.
	86	+ * Text can be quoted using single quotes (<code>'</code>) to avoid
	87	+ * interpretation.
	88	+ * <code>"''"</code> represents a single quote.
	89	+ * All other characters are not interpreted; they're simply copied into the
	90	+ * output string during formatting or matched against the input string
	91	+ * during parsing.
	92	+ * <p>
	93	+ * The following pattern letters are defined (all other characters from
	94	+ * <code>'A'</code> to <code>'Z'</code> and from <code>'a'</code> to
	95	+ * <code>'z'</code> are reserved):

	215	+ * Pattern letters are usually repeated, as their number determines the
	216	+ * exact presentation:
	217	+ * <ul>
	218	+ * <li><strong><a name="text">Text:</a></strong>
	219	+ * For formatting, if the number of pattern letters is 4 or more,
	220	+ * the full form is used; otherwise a short or abbreviated form
	221	+ * is used if available.
	222	+ * For parsing, both forms are accepted, independent of the number
	223	+ * of pattern letters.<br><br></li>
	224	+ * <li><strong><a name="number">Number:</a></strong>
	225	+ * For formatting, the number of pattern letters is the minimum
	226	+ * number of digits, and shorter numbers are zero-padded to this amount.
	227	+ * For parsing, the number of pattern letters is ignored unless
	228	+ * it's needed to separate two adjacent fields.<br><br></li>
	229	+ * <li><strong><a name="year">Year:</a></strong>
	230	+ * If the formatter's {@link #getCalendar() Calendar} is the Gregorian
	231	+ * calendar, the following rules are applied.<br>
	232	+ * <ul>
	233	+ * <li>For formatting, if the number of pattern letters is 2, the year
	234	+ * is truncated to 2 digits; otherwise it is interpreted as a
	235	+ * <a href="#number">number</a>.
	236	+ * <li>For parsing, if the number of pattern letters is more than 2,
	237	+ * the year is interpreted literally, regardless of the number of
	238	+ * digits. So using the pattern "MM/dd/yyyy", "01/11/12" parses to
	239	+ * Jan 11, 12 A.D.
	240	+ * <li>For parsing with the abbreviated year pattern ("y" or "yy"),
	241	+ * <code>SimpleDateFormat</code> must interpret the abbreviated year
	242	+ * relative to some century. It does this by adjusting dates to be
	243	+ * within 80 years before and 20 years after the time the <code>SimpleDateFormat</code>
	244	+ * instance is created. For example, using a pattern of "MM/dd/yy" and a
	245	+ * <code>SimpleDateFormat</code> instance created on Jan 1, 1997, the string
	246	+ * "01/11/12" would be interpreted as Jan 11, 2012 while the string "05/04/64"
	247	+ * would be interpreted as May 4, 1964.
	248	+ * During parsing, only strings consisting of exactly two digits, as defined by
	249	+ * {@link Character#isDigit(char)}, will be parsed into the default century.
	250	+ * Any other numeric string, such as a one digit string, a three or more digit
	251	+ * string, or a two digit string that isn't all digits (for example, "-1"), is
	252	+ * interpreted literally. So "01/02/3" or "01/02/003" are parsed, using the
	253	+ * same pattern, as Jan 2, 3 AD. Likewise, "01/02/-3" is parsed as Jan 2, 4 BC.
	254	+ * </ul>
	255	+ * Otherwise, calendar system specific forms are applied.
	256	+ * For both formatting and parsing, if the number of pattern
	257	+ * letters is 4 or more, a calendar specific {@linkplain
	258	+ * Calendar#LONG long form} is used. Otherwise, a calendar
	259	+ * specific {@linkplain Calendar#SHORT short or abbreviated form}
	260	+ * is used.<br>
	261	+ * <br>
	262	+ * If week year {@code 'Y'} is specified and the {@linkplain
	263	+ * #getCalendar() calendar} doesn't support any <a
	264	+ * href="../util/GregorianCalendar.html#week_year"> week
	265	+ * years</a>, the calendar year ({@code 'y'}) is used instead. The
	266	+ * support of week years can be tested with a call to {@link
	267	+ * DateFormat#getCalendar() getCalendar()}.{@link
	268	+ * java.util.Calendar#isWeekDateSupported()
	269	+ * isWeekDateSupported()}.<br><br></li>
	270	+ * <li><strong><a name="month">Month:</a></strong>
	271	+ * If the number of pattern letters is 3 or more, the month is
	272	+ * interpreted as <a href="#text">text</a>; otherwise,
	273	+ * it is interpreted as a <a href="#number">number</a>.<br><br></li>
	274	+ * <li><strong><a name="timezone">General time zone:</a></strong>
	275	+ * Time zones are interpreted as <a href="#text">text</a> if they have
	276	+ * names. For time zones representing a GMT offset value, the
	277	+ * following syntax is used:
	278	+ * <pre>

	331	+ * {@code "GMT+05:30"}, {@code "+05"} is produced.
	332	+ *
	333	+ * <p>For parsing, {@code "Z"} is parsed as the UTC time zone designator.

	341	+ * <code>SimpleDateFormat</code> also supports <em>localized date and time
