/**
* Extended version of 'format()' with variable-length formatting codes
*
* Most codes reproduce the no of digits equal to the length of the code,
* for example, 'YYY' 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 'NPYYY', which will return
* '89'.
*
* For negative values, the sign will be discarded, unless the 'S' 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:
*
* <code>YYYY</code> returns '2007'
* <code>SYYYY</code> returns ' 2007'
* <code>NPSYYYY</code> returns '2007'
*
* The no-padding modifier 'NP' can be used with numeric codes to
* suppress leading (or trailing in the case of code 'F') noughts, and
* with character-returning codes such as 'DAY' 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:
*
* <code>Day</code> returns 'Monday ' because the maximum length of
* this code is 'Wednesday';
* <code>NPDay</code> 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 'MONTH', will
* set the capitalization according to the code, so for example:
*
* <code>MONTH</code> returns upper-case spelling, e.g. 'JANUARY'
* <code>Month</code> returns spelling with first character of each word
* capitalized, e.g. 'January'
* <code>month</code> returns lower-case spelling, e.g. 'january'
*
* Where it makes sense, numeric codes can be combined with a following
* 'SP' code which spells out the number, or with a 'TH' code, which
* renders the code as an ordinal ('TH' only works in English), for
* example, for 31st December:
*
* <code>DD</code> returns '31'
* <code>DDTH</code> returns '31ST'
* <code>DDth</code> returns '31st'
* <code>DDSP</code> returns 'THIRTY-ONE'
* <code>DDSp</code> returns 'Thirty-one'
* <code>DDsp</code> returns 'thirty-one'
* <code>DDSPTH</code> returns 'THIRTY-FIRST'
* <code>DDSpth</code> returns 'Thirty-first'
* <code>DDspth</code> returns 'thirty-first'
*
*
* All formatting options:
*
* <code>-</code> All punctuation and white-space is reproduced unchanged
* <code>/</code>
* <code>,</code>
* <code>.</code>
* <code>;</code>
* <code>:</code>
* <code> </code>
* <code>"text"</code> Quoted text is reproduced unchanged (escape using
* '\')
* <code>AD</code> AD indicator with or without full stops; N.B. if you
* are using 'Astronomical' year numbering then 'A.D./B.C.'
* indicators will be out for negative years
* <code>A.D.</code>
* <code>AM</code> Meridian indicator with or without full stops
* <code>A.M.</code>
* <code>BC</code> BC indicator with or without full stops
* <code>B.C.</code>
* <code>BCE</code> BCE indicator with or without full stops
* <code>B.C.E.</code>
* <code>CC</code> Century, i.e. the year divided by 100, discarding the
* remainder; 'S' prefixes negative years with a minus sign
* <code>SCC</code>
* <code>CE</code> CE indicator with or without full stops
* <code>C.E.</code>
* <code>D</code> Day of week (0-6), where 0 represents Sunday
* <code>DAY</code> Name of day, padded with blanks to display width of the
* widest name of day in the locale of the machine
* <code>DD</code> Day of month (1-31)
* <code>DDD</code> Day of year (1-366)
* <code>DY</code> Abbreviated name of day
* <code>FFF</code> Fractional seconds; no radix character is printed. The
* no of 'F's determines the no of digits of the
* part-second to return; e.g. 'HH:MI:SS.FF'
* <code>F[integer]</code> The integer after 'F' specifies the number of
* digits of the part-second to return. This is an
* alternative to using F[integer], and 'F3' is thus
* equivalent to using 'FFF'.
* <code>HH</code> Hour of day (0-23)
* <code>HH12</code> Hour of day (1-12)
* <code>HH24</code> Hour of day (0-23)
* <code>ID</code> Day of week (1-7) based on the ISO standard
* <code>IW</code> Week of year (1-52 or 1-53) based on the ISO standard
* <code>IYYY</code> 4-digit year based on the ISO 8601 standard; 'S'
* prefixes negative years with a minus sign
* <code>SIYYY</code>
* <code>IYY</code> Last 3, 2, or 1 digit(s) of ISO year
* <code>IY</code>
* <code>I</code>
* <code>J</code> Julian day - the number of days since Monday, 24th
* November, 4714 B.C. (proleptic Gregorian calendar)
* <code>MI</code> Minute (0-59)
* <code>MM</code> Month (01-12; January = 01)
* <code>MON</code> Abbreviated name of month
* <code>MONTH</code> Name of month, padded with blanks to display width of
* the widest name of month in the date language used for
* <code>PM</code> Meridian indicator with or without full stops
* <code>P.M.</code>
* <code>Q</code> Quarter of year (1, 2, 3, 4; January - March = 1)
* <code>RM</code> Roman numeral month (I-XII; January = I); N.B. padded
* with leading spaces.
* <code>SS</code> Second (0-59)
* <code>SSSSS</code> Seconds past midnight (0-86399)
* <code>TZC</code> 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 'TZR').
* <code>TZH</code> Time zone hour; 'S' 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 'NP'). Also note that if you combine
* with the 'SP' code, the sign will not be spelled out.
* (I.e. 'STZHSp' will produce '+One', for example, and
* not 'Plus One'.
* 'TZH:TZM' will produce, for example, '+05:30'. (Also
* see 'TZM' format code)
* <code>STZH</code>
* <code>TZI</code> Whether or not the date is in Summer time (daylight
* saving time). Returns '1' if Summer time, else '0'.
* <code>TZM</code> Time zone minute, without any +/- sign. (Also see
* 'TZH' format element)
* <code>TZN</code> 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 'TZR').
* <code>TZO</code> Time zone offset in ISO 8601 form - that is, 'Z' if
* UTC, else [+/-][hh]:[mm] (which would be equivalent
* to 'STZH:TZM'). Note that this result is right padded
* with spaces by default, (i.e. if 'Z').
* <code>TZS</code> Time zone offset in seconds; 'S' prefixes negative
* sign with minus sign '-' if negative, and no sign if
* positive (i.e. -43200 to 50400).
* <code>STZS</code>
* <code>TZR</code> Time zone region, that is, the name or ID of the time
* zone e.g. 'Europe/London'. This value is unique for
* each time zone.
* <code>U</code> Seconds since the Unix Epoch -
* January 1 1970 00:00:00 GMT
* <code>W</code> 'Absolute' week of month (1-5), counting week 1 as
* 1st-7th of the year, regardless of the day
* <code>W1</code> Week of year (1-54), counting week 1 as the week that
* contains 1st January
* <code>W4</code> Week of year (1-53), counting week 1 as the week that
* contains 4th January (i.e. first week with at least 4
* days)
* <code>W7</code> Week of year (1-53), counting week 1 as the week that
* contains 7th January (i.e. first full week)
* <code>WW</code> 'Absolute' week of year (1-53), counting week 1 as
* 1st-7th of the year, regardless of the day
* <code>YEAR</code> Year, spelled out; 'S' prefixes negative years with
* 'MINUS'; N.B. 'YEAR' differs from 'YYYYSP' in that the
* first will render 1923, for example, as 'NINETEEN
* TWENTY-THREE, and the second as 'ONE THOUSAND NINE
* HUNDRED TWENTY-THREE'
* <code>SYEAR</code>
* <code>YYYY</code> 4-digit year; 'S' prefixes negative years with a minus
* sign
* <code>SYYYY</code>
* <code>YYY</code> Last 3, 2, or 1 digit(s) of year
* <code>YY</code>
* <code>Y</code>
* <code>Y,YYY</code> Year with thousands-separator in this position; five
* possible separators
* <code>Y.YYY</code>
* <code>YｷYYY</code> N.B. space-dot (mid-dot, interpunct) is valid only in
* ISO 8859-1 (so take care when using UTF-8 in
* particular)
* <code>Y'YYY</code>
* <code>Y YYY</code>
*
* In addition the following codes can be used in combination with other
* codes;
* Codes that modify the next code in the format string:
*
* <code>NP</code> 'No Padding' - Returns a value with no trailing blanks
* and no leading or trailing noughts; N.B. that the
* 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 'MM'):
*
* <code>TH</code> Ordinal number
* <code>SP</code> Spelled cardinal number
* <code>SPTH</code> Spelled ordinal number (combination of 'SP' and 'TH'
* in any order)
* <code>THSP</code>
*
* Code 'SP' can have the following three variations (which can also be used
* in combination with 'TH'):
*
* <code>SP</code> returns upper-case spelling, e.g. 'FOUR HUNDRED'
* <code>Sp</code> returns spelling with first character of each word
* capitalized, e.g. 'Four Hundred'
* <code>sp</code> returns lower-case spelling, e.g. 'four hundred'
*
* Code 'TH' can have the following two variations (although in combination
* with code 'SP', the case specification of 'SP' takes precedence):
*
* <code>TH</code> returns upper-case ordinal suffix, e.g. 400TH
* <code>th</code> returns lower-case ordinal suffix, e.g. 400th
*
* @param string $ps_format format string for returned date/time
