/**
* <code>SimpleDateFormat</code> is a concrete class for formatting and
* parsing dates in a locale-sensitive manner. It allows for formatting
* (date -> text), parsing (text -> date), and normalization.
*
* <p>
* <code>SimpleDateFormat</code> allows you to start by choosing
* any user-defined patterns for date-time formatting. However, you
* are encouraged to create a date-time formatter with either
* <code>getTimeInstance</code>, <code>getDateInstance</code>, or
* <code>getDateTimeInstance</code> in <code>DateFormat</code>. Each
* with a default format pattern. You may modify the format pattern
* using the <code>applyPattern</code> methods as desired.
* For more information on using these methods, see
* {@link DateFormat}.
*
* <h4>Date and Time Patterns</h4>
* <p>
* Date and time formats are specified by <em>date and time pattern</em>
* strings.
* Within date and time pattern strings, unquoted letters from
* <code>'A'</code> to <code>'Z'</code> and from <code>'a'</code> to
* <code>'z'</code> are interpreted as pattern letters representing the
* components of a date or time string.
* Text can be quoted using single quotes (<code>'</code>) to avoid
* interpretation.
* <code>"''"</code> represents a single quote.
* All other characters are not interpreted; they're simply copied into the
* output string during formatting or matched against the input string
* during parsing.
* <p>
* The following pattern letters are defined (all other characters from
* <code>'A'</code> to <code>'Z'</code> and from <code>'a'</code> to
* <code>'z'</code> are reserved):
* <blockquote>
* <table border=0 cellspacing=3 cellpadding=0 summary="Chart shows pattern letters, date/time component, presentation, and examples.">

* Pattern letters are usually repeated, as their number determines the
* exact presentation:
* <ul>
* <li><strong><a name="text">Text:</a></strong>
* For formatting, if the number of pattern letters is 4 or more,
* the full form is used; otherwise a short or abbreviated form
* is used if available.
* For parsing, both forms are accepted, independent of the number
* of pattern letters.<br><br></li>
* <li><strong><a name="number">Number:</a></strong>
* For formatting, the number of pattern letters is the minimum
* number of digits, and shorter numbers are zero-padded to this amount.
* For parsing, the number of pattern letters is ignored unless
* it's needed to separate two adjacent fields.<br><br></li>
* <li><strong><a name="year">Year:</a></strong>
* If the formatter's {@link #getCalendar() Calendar} is the Gregorian
* calendar, the following rules are applied.<br>
* <ul>
* <li>For formatting, if the number of pattern letters is 2, the year
* is truncated to 2 digits; otherwise it is interpreted as a
* <a href="#number">number</a>.
* <li>For parsing, if the number of pattern letters is more than 2,
* the year is interpreted literally, regardless of the number of
* Jan 11, 12 A.D.
* <li>For parsing with the abbreviated year pattern ("y" or "yy"),
* <code>SimpleDateFormat</code> 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 <code>SimpleDateFormat</code>
* <code>SimpleDateFormat</code> 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
* {@link Character#isDigit(char)}, 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, using the
* same pattern, as Jan 2, 3 AD. Likewise, "01/02/-3" is parsed as Jan 2, 4 BC.
* </ul>
* Otherwise, calendar system specific forms are applied.
* For both formatting and parsing, if the number of pattern
* letters is 4 or more, a calendar specific {@linkplain
* Calendar#LONG long form} is used. Otherwise, a calendar
* specific {@linkplain Calendar#SHORT short or abbreviated form}
* is used.<br>
* <br>
* If week year {@code 'Y'} is specified and the {@linkplain
* #getCalendar() calendar} doesn't support any <a
* href="../util/GregorianCalendar.html#week_year"> week
* years</a>, the calendar year ({@code 'y'}) is used instead. The
* support of week years can be tested with a call to {@link
* DateFormat#getCalendar() getCalendar()}.{@link
* java.util.Calendar#isWeekDateSupported()
* isWeekDateSupported()}.<br><br></li>
* <li><strong><a name="month">Month:</a></strong>
* If the number of pattern letters is 3 or more, the month is
* interpreted as <a href="#text">text</a>; otherwise,
* it is interpreted as a <a href="#number">number</a>.<br><br></li>
* <li><strong><a name="timezone">General time zone:</a></strong>
* Time zones are interpreted as <a href="#text">text</a> if they have
* names. For time zones representing a GMT offset value, the
* following syntax is used:
* <pre>
* <a name="GMTOffsetTimeZone"><i>GMTOffsetTimeZone:</i></a>
* <code>GMT</code> <i>Sign</i> <i>Hours</i> <code>:</code> <i>Minutes</i>
* <i>Sign:</i> one of
* <code>+ -</code>
* <i>Hours:</i>
* <i>Digit</i>
* <i>Digit</i> <i>Digit</i>
* <i>Minutes:</i>
* <i>Digit</i> <i>Digit</i>
* <i>Digit:</i> one of
* <code>0 1 2 3 4 5 6 7 8 9</code></pre>
* <i>Hours</i> must be between 0 and 23, and <i>Minutes</i> must be between
* 00 and 59. The format is locale independent and digits must be taken
* from the Basic Latin block of the Unicode standard.
* <p>For parsing, <a href="#rfc822timezone">RFC 822 time zones</a> are also
* accepted.<br><br></li>
* <li><strong><a name="rfc822timezone">RFC 822 time zone:</a></strong>
* For formatting, the RFC 822 4-digit time zone format is used:
*
* <pre>
* <i>RFC822TimeZone:</i>
* <i>Sign</i> <i>TwoDigitHours</i> <i>Minutes</i>
* <i>TwoDigitHours:</i>
* <i>Digit Digit</i></pre>
* <i>TwoDigitHours</i> must be between 00 and 23. Other definitions
* are as for <a href="#timezone">general time zones</a>.
*
* <p>For parsing, <a href="#timezone">general time zones</a> are also
* accepted.
* <li><strong><a name="iso8601timezone">ISO 8601 Time zone:</a></strong>
* The number of pattern letters designates the format for both formatting
* and parsing as follows:
* <pre>
* <i>ISO8601TimeZone:</i>
* <i>OneLetterISO8601TimeZone</i>
* <i>TwoLetterISO8601TimeZone</i>
* <i>ThreeLetterISO8601TimeZone</i>
* <i>OneLetterISO8601TimeZone:</i>
* <i>Sign</i> <i>TwoDigitHours</i>
* {@code Z}
* <i>TwoLetterISO8601TimeZone:</i>
* <i>Sign</i> <i>TwoDigitHours</i> <i>Minutes</i>
* {@code Z}
* <i>ThreeLetterISO8601TimeZone:</i>
* <i>Sign</i> <i>TwoDigitHours</i> {@code :} <i>Minutes</i>
* {@code Z}</pre>
* Other definitions are as for <a href="#timezone">general time zones</a> or
* <a href="#rfc822timezone">RFC 822 time zones</a>.
*
* <p>For formatting, if the offset value from GMT is 0, {@code "Z"} is
* produced. If the number of pattern letters is 1, any fraction of an hour
* is ignored. For example, if the pattern is {@code "X"} and the time zone is
* {@code "GMT+05:30"}, {@code "+05"} is produced.
*
* <p>For parsing, {@code "Z"} is parsed as the UTC time zone designator.
* <a href="#timezone">General time zones</a> are <em>not</em> accepted.
*
* <p>If the number of pattern letters is 4 or more, {@link
* IllegalArgumentException} is thrown when constructing a {@code
* SimpleDateFormat} or {@linkplain #applyPattern(String) applying a
* pattern}.
* </ul>
* <code>SimpleDateFormat</code> also supports <em>localized date and time
* pattern</em> strings. In these strings, the pattern letters described above
* may be replaced with other, locale dependent, pattern letters.
* <code>SimpleDateFormat</code> does not deal with the localization of text
* other than the pattern letters; that's up to the client of the class.
* <p>
*
* <h4>Examples</h4>
*
* The following examples show how date and time patterns are interpreted in
* the U.S. locale. The given date and time are 2001-07-04 12:08:56 local time
* in the U.S. Pacific Time time zone.
