/**
* Whether to correct, by adding the local Summer time offset, the
* specified time if it falls in the 'skipped hour' (encountered
* when the clocks go forward).
*
* N.B. if specified as 'false', and if a time zone that adjusts
* for Summer time is specified, then an object of this class will
* be set to a semi-invalid state if an invalid time is set. That
* is, an error will not be returned, unless the user then calls
* a function, directly or indirectly, that accesses the time
* part of the object. So, for example, if the user calls:
*
* <code>$date_object->formatLikeSQL('HH.MI.SS');</code>
*
* or:
*
* <code>$date_object->addSeconds(30);</code>
*
* an error will be returned if the time is invalid. However,
* if the user calls:
*
* <code>$date_object->addDays(1);</code>
*
* for example, such that the time is no longer invalid, then the
* object will no longer be in this invalid state. This behaviour
* is intended to minimize unexpected errors when a user uses the
* class to do addition with days only, and does not intend to
* access the time.
*
* Of course, this constant will be unused if the user chooses to
* work in UTC or a time zone without Summer time, in which case
* this situation will never arise.
*
* This constant is set to 'true' by default for backwards-compatibility
* reasons, however, you are recommended to set it to 'false'. Note that the
* behaviour is not intended to match that of previous versions of the class
* in terms of ignoring the Summer time offset when making calculations which
* involve dates in both standard and Summer time - this was recognized as a
* bug - but in terms of returning a PEAR error object when the user sets the
* object to an invalid date (i.e. a time in the hour which is skipped when
* the clocks go forwards, which in Europe would be a time such as 01.30).
* Backwards compatibility here means that the behaviour is the same as it
* used to be, less the bug.
*
* Note that this problem is not an issue for the user if any of these
* conditions are satisfied:
*
* <ol>
* <li>the user uses a time zone that does not observe Summer time, e.g. UTC</li>
* <li>the user never accesses the time, that is, he never makes a call to
* {@link Date::getHour()} or {@link Date::formatLikeStrftime()} using
* format code '<b>%H</b>', for example, even if he sets the time to
* something invalid</li>
* <li>the user sets DATE_CORRECTINVALIDTIME_DEFAULT to true</li>

* day of the month [01-31]
* - <b>ISO week date</b>: <b>YYYY-Www-D</b> (extended format) or
* <b>YYYYWwwD</b> (basic format), where [YYYY]
* indicates the ISO year (slightly different from the
* calendar year (see below)), [Www] indicates the ISO

* {@link http://en.wikipedia.org/wiki/ISO_week_date}.)
* - <b>Ordinal date</b>: <b>YYYY-DDD</b> (extended format) or
* <b>YYYYDDD</b> (basic format), where [YYYY]
* indicates the four-digit year (0000-9999) and [DDD]
* indicates the day of the year (001-366)

* - <b>hh:mm</b> (extended format) or <b>hhmm</b> (basic format)

/**
* Formats the date according to the specified formatting code string,
* based on SQL date-formatting codes
*
* Most codes reproduce the no of digits equal to the length of the
* code, for example, '<b>YYY</b>' will return the last 3 digits of
* the year, and so the year 2007 will produce '007', and the year 89
* will produce '089', unless the no-padding code is used as in
* '<b>NPYYY</b>', which will return '89'.
*
* For negative values, the sign will be discarded, unless the
* '<b>S</b>' code is used in combination, but note that for positive
* values the value will be padded with a leading space unless it
* is suppressed with the no-padding modifier, for example for 2007:
*
* - <b>YYYY</b> - returns '2007'
* - <b>SYYYY</b> - returns ' 2007'
* - <b>NPSYYYY</b> - returns '2007'
*
* The no-padding modifier '<b>NP</b>' can be used with numeric codes
* to suppress leading (or trailing in the case of code '<b>F</b>')
* noughts, and with character-returning codes such as '<b>DAY</b>'
* to suppress trailing spaces, which will otherwise be padded to the
* maximum possible length of the return-value of the code; for
* example, for Monday:
*
* - <b>Day</b> - returns 'Monday ' because the maximum length of
* this code is 'Wednesday';
* - <b>NPDay</b> - returns 'Monday'
*
* N.B. this code affects the code immediately following only, and
* without this code the default is always to apply padding.
*
* Most character-returning codes, such as '<b>MONTH</b>', will
* set the capitalization according to the code, so for example:
*
* - <b>MONTH</b> - returns upper-case spelling, e.g. 'JANUARY'
* - <b>Month</b> - returns spelling with first character of each word
* capitalized, e.g. 'January'
* - <b>month</b> - returns lower-case spelling, e.g. 'january'
*
* Where it makes sense, numeric codes can be combined with a following
* '<b>SP</b>' code which spells out the number, or with a '<b>TH</b>'
* code, which renders the code as an ordinal ('<b>TH</b>' only works
* in English), for example, for 31st December:
*
* - <b>DD</b> - returns '31'
* - <b>DDTH</b> - returns '31ST'
* - <b>DDth</b> - returns '31st'
* - <b>DDSP</b> - returns 'THIRTY-ONE'
* - <b>DDSp</b> - returns 'Thirty-one'
* - <b>DDsp</b> - returns 'thirty-one'
* - <b>DDSPTH</b> - returns 'THIRTY-FIRST'
* - <b>DDSpth</b> - returns 'Thirty-first'
* - <b>DDspth</b> - returns 'thirty-first'
*
*
* All formatting options:
*
* - <b>-</b> (All punctuation and white-space is reproduced unchanged)
* - <b>/</b>
* - <b>,</b>
* - <b>.</b>
* - <b>;</b>

* - <b>A.M.</b>
* - <b>BC</b> - BC indicator with or without full stops
* - <b>B.C.</b>
* - <b>BCE</b> - BCE indicator with or without full stops
* - <b>B.C.E.</b>
* - <b>CC</b> - Century, i.e. the year divided by 100, discarding the
* remainder; '<b>S</b>' prefixes negative years with a
* minus sign
* - <b>SCC</b>
* - <b>CE</b> - CE indicator with or without full stops
* - <b>C.E.</b>
* - <b>D</b> - Day of week (0-6), where 0 represents Sunday
* - <b>DAY</b> - Name of day, padded with blanks to display width of the
* widest name of day in the locale of the machine
* - <b>DD</b> - Day of month (1-31)
* - <b>DDD</b> - Day of year (1-366)
* - <b>DY</b> - Abbreviated name of day
* - <b>FFF</b> - Fractional seconds; no radix character is printed. The
* no of '<b>F</b>'s determines the no of digits of the
* part-second to return; e.g. 'HH:MI:SS.FF'
* - <b>F[integer]</b> - The integer after '<b>F</b>' specifies the
* number of digits of the part-second to return.
* This is an alternative to using several
* '<b>F</b>'s in sequence, and '<b>F3</b>' is thus
* equivalent to using '<b>FFF</b>'.
* - <b>HH</b> - Hour of day (0-23)
* - <b>HH12</b> - Hour of day (1-12)
* - <b>HH24</b> - Hour of day (0-23)

* - <b>MI</b> - Minute (0-59)
* - <b>MM</b> - Month (01-12; January = 01)
* - <b>MON</b> - Abbreviated name of month
* - <b>MONTH</b> - Name of month, padded with blanks to display width of
* the widest name of month in the date language used for
* - <b>PM</b> - Meridian indicator with or without full stops
* - <b>P.M.</b>
* - <b>Q</b> - Quarter of year (1, 2, 3, 4; January - March = 1)
* - <b>RM</b> - Roman numeral month (I-XII; January = I); N.B. padded
* with leading spaces.
* - <b>SS</b> - Second (0-59)
* - <b>SSSSS</b> - Seconds past midnight (0-86399)
* - <b>TZC</b> - Abbreviated form of time zone name, e.g. 'GMT', or the
* abbreviation for Summer time if the date falls in Summer
* time, e.g. 'BST'.
* N.B. this is not a unique identifier - for this purpose
* use the time zone region (code '<b>TZR</b>').
* - <b>TZH</b> - Time zone hour; '<b>S</b>' prefixes the hour with the
* correct sign, (+/-), which otherwise is not displayed.
* Note that the leading nought can be suppressed with the
* no-padding code '<b>NP</b>'). Also note that if you
* combine with the '<b>SP</b>' code, the sign will not be
* spelled out. (I.e. '<b>STZHSp</b>' will produce '+One',
* for example, and not 'Plus One'.
* '<b>TZH:TZM</b>' will produce, for example, '+05:30'.
* (Also see '<b>TZM</b>' format code)
* - <b>STZH</b>
* - <b>TZI</b> - Whether or not the date is in Summer time (daylight
* saving time). Returns '1' if Summer time, else '0'.
* - <b>TZM</b> - Time zone minute, without any +/- sign. (Also see
* '<b>TZH</b>' format element)
* - <b>TZN</b> - Long form of time zone name, e.g.
* 'Greenwich Mean Time', or the name of the Summer time if
* the date falls in Summer time, e.g.
* 'British Summer Time'. N.B. this is not a unique
* identifier - for this purpose use the time zone region
* (code '<b>TZR</b>').
* - <b>TZO</b> - Time zone offset in ISO 8601 form - that is, 'Z' if
* UTC, else [+/-][hh]:[mm] (which would be equivalent
* to '<b>STZH:TZM</b>'). Note that this result is right
* padded.
* with spaces by default, (i.e. if 'Z').
* - <b>TZS</b> - Time zone offset in seconds; '<b>S</b>' prefixes
* negative sign with minus sign '-' if negative, and no
* sign if positive (i.e. -43200 to 50400).
* - <b>STZS</b>
* - <b>TZR</b> - Time zone region, that is, the name or ID of the time

* each time zone.
* - <b>U</b> - Seconds since the Unix Epoch -
* January 1 1970 00:00:00 GMT
* - <b>W</b> - 'Absolute' week of month (1-5), counting week 1 as

* - <b>WW</b> - 'Absolute' week of year (1-53), counting week 1 as
* 1st-7th of the year, regardless of the day
* - <b>YEAR</b> - Year, spelled out; '<b>S</b>' prefixes negative
* years with 'MINUS'; N.B. '<b>YEAR</b>' differs from
* '<b>YYYYSP</b>' in that the first will render 1923,
* for example, as 'NINETEEN TWENTY-THREE, and the

* - <b>SYEAR</b>
* - <b>YYYY</b> - 4-digit year; '<b>S</b>' prefixes negative years

* default is to include this padding in the return string.
* N.B. affects the code immediately following only.
*
* Codes that modify the previous code in the format string (can only
* be used with integral codes such as '<b>MM</b>'):
*
* - <b>TH</b> - Ordinal number
* - <b>SP</b> - Spelled cardinal number
* - <b>SPTH</b> - Spelled ordinal number (combination of '<b>SP</b>'
* and '<b>TH</b>' in any order)
* - <b>THSP</b>
*
* Code '<b>SP</b>' can have the following three variations (which can

* A time span is defined as a unsigned no of days, hours, minutes

*
* A span is added (and subtracted) according to the following logic:
*
* Hours, minutes and seconds are added such that if they fall over
* a leap second, the leap second is ignored, and not counted.
* For example, if a leap second occurred at 23.59.60, the
* following calculations:
*
* - 23.59.59 + one second
* - 23.59.00 + one minute
* - 23.00.00 + one hour
*
* would all produce 00.00.00 the next day.
*
* A day is treated as equivalent to 24 hours, so if the clocks
* went backwards at 01.00, and one day was added to the time
* 00.30, the result would be 23.30 the same day.
*
* This is the implementation which is thought to yield the behaviour
* that the user is most likely to expect, or in another way of
* looking at it, it is the implementation that produces the least
* unexpected behaviour. It basically works in hours, that is, a day
* is treated as exactly equivalent to 24 hours, and minutes and
* seconds are treated as equivalent to 1/60th and 1/3600th of an
* hour. It should be obvious that working in days is impractical;
* working in seconds is problematic when it comes to adding days
* that fall over leap seconds, where it would appear to most users
* that the function adds only 23 hours, 59 minutes and 59 seconds.
* It is also problematic to work in any kind of mixture of days,
* hours, minutes, and seconds, because then the addition of a span
* would sometimes depend on which order you add the constituent
* parts, which undermines the concept of a span altogether.
*
* If you want alternative functionality, you must use a mixture of
* the following functions instead:
*
* - {@link Date::addYears()}
* - {@link Date::addMonths()}
* - {@link Date::addDays()}
* - {@link Date::addHours()}

*
* Note that the stored date (i.e. the day/month/year), is set more
* strictly: it is not possible to set an invalid day/month/year
* using {@link Date::setDate()} and it is only possible to do so with
* {@link setYear()} etc. for backwards-compatibility (and anyway, this
* can be switched off by default by setting
* {@link DATE_VALIDATE_DATE_BY_DEFAULT} to 'true').
*
* The object is able to store an invalid time because a user might
* unwittingly and correctly store a valid time, and then add one day so
* as to put the object in the 'skipped' hour (when the clocks go forward).
* This could be corrected by a conversion to Summer time (by adding one
* hour); however, if the user then added another day, and had no need for
* or interest in the time anyway, the behaviour may be rather unexpected.
* And anyway in this situation, the time originally specified would now,

* not in any way make use of or request the time while it is in this
* semi-invalid state, in order to allow for for the fact that he might be
