+ADOdb Date Library, part of the ADOdb abstraction library
+
+Latest version is available at http://adodb.org/
+
+@version v5.20.14 06-Jan-2019
+@copyright (c) 2000-2013 John Lim (jlim#natsoft.com). All rights reserved.
+@copyright (c) 2014 Damien Regad, Mark Newnham and the ADOdb community
+
+PHP native date functions use integer timestamps for computations.
+Because of this, dates are restricted to the years 1901-2038 on Unix
+and 1970-2038 on Windows due to integer overflow for dates beyond
+those years. This library overcomes these limitations by replacing the
+native function's signed integers (normally 32-bits) with PHP floating
+point numbers (normally 64-bits).
+
+Dates from 100 A.D. to 3000 A.D. and later
+have been tested. The minimum is 100 A.D. as <100 will invoke the
+2 => 4 digit year conversion. The maximum is billions of years in the
+future, but this is a theoretical limit as the computation of that year
+would take too long with the current implementation of adodb_mktime().
+
+This library replaces native functions as follows:
+
+<pre>
+ getdate() with adodb_getdate()
+ date() with adodb_date()
+ gmdate() with adodb_gmdate()
+ mktime() with adodb_mktime()
+ gmmktime() with adodb_gmmktime()
+ strftime() with adodb_strftime()
+ strftime() with adodb_gmstrftime()
+</pre>
+
+The parameters are identical, except that adodb_date() accepts a subset
+of date()'s field formats. Mktime() will convert from local time to GMT,
+and date() will convert from GMT to local time, but daylight savings is
+not handled currently.
+
+This library is independant of the rest of ADOdb, and can be used
+as standalone code.
+
+PERFORMANCE
+
+For high speed, this library uses the native date functions where
+possible, and only switches to PHP code when the dates fall outside
+the 32-bit signed integer range.
+
+GREGORIAN CORRECTION
+
+Pope Gregory shortened October of A.D. 1582 by ten days. Thursday,
+October 4, 1582 (Julian) was followed immediately by Friday, October 15,
+1582 (Gregorian).
+
+Since 0.06, we handle this correctly, so:
+
+adodb_mktime(0,0,0,10,15,1582) - adodb_mktime(0,0,0,10,4,1582)
+ == 24 * 3600 (1 day)

+
+FUNCTION DESCRIPTIONS
+
+** FUNCTION adodb_time()
+
+Returns the current time measured in the number of seconds since the Unix Epoch (January 1 1970 00:00:00 GMT) as an unsigned integer.
+
+** FUNCTION adodb_getdate($date=false)
+
+Returns an array containing date information, as getdate(), but supports
+dates greater than 1901 to 2038. The local date/time format is derived from a
+heuristic the first time adodb_getdate is called.
+
+
+** FUNCTION adodb_date($fmt, $timestamp = false)
+
+Convert a timestamp to a formatted local date. If $timestamp is not defined, the
+current timestamp is used. Unlike the function date(), it supports dates
+outside the 1901 to 2038 range.
+
+The format fields that adodb_date supports:
+
+<pre>
+ a - "am" or "pm"
+ A - "AM" or "PM"
+ d - day of the month, 2 digits with leading zeros; i.e. "01" to "31"
+ D - day of the week, textual, 3 letters; e.g. "Fri"
+ F - month, textual, long; e.g. "January"
+ g - hour, 12-hour format without leading zeros; i.e. "1" to "12"
+ G - hour, 24-hour format without leading zeros; i.e. "0" to "23"
+ h - hour, 12-hour format; i.e. "01" to "12"
+ H - hour, 24-hour format; i.e. "00" to "23"
+ i - minutes; i.e. "00" to "59"
+ j - day of the month without leading zeros; i.e. "1" to "31"
+ l (lowercase 'L') - day of the week, textual, long; e.g. "Friday"
+ L - boolean for whether it is a leap year; i.e. "0" or "1"
+ m - month; i.e. "01" to "12"
+ M - month, textual, 3 letters; e.g. "Jan"
+ n - month without leading zeros; i.e. "1" to "12"
+ O - Difference to Greenwich time in hours; e.g. "+0200"
+ Q - Quarter, as in 1, 2, 3, 4
+ r - RFC 2822 formatted date; e.g. "Thu, 21 Dec 2000 16:01:07 +0200"
+ s - seconds; i.e. "00" to "59"
+ S - English ordinal suffix for the day of the month, 2 characters;
+ i.e. "st", "nd", "rd" or "th"
+ t - number of days in the given month; i.e. "28" to "31"
+ T - Timezone setting of this machine; e.g. "EST" or "MDT"
+ U - seconds since the Unix Epoch (January 1 1970 00:00:00 GMT)
+ w - day of the week, numeric, i.e. "0" (Sunday) to "6" (Saturday)
+ Y - year, 4 digits; e.g. "1999"
+ y - year, 2 digits; e.g. "99"
+ z - day of the year; i.e. "0" to "365"
+ Z - timezone offset in seconds (i.e. "-43200" to "43200").
+ The offset for timezones west of UTC is always negative,
+ and for those east of UTC is always positive.
+</pre>
+
+Unsupported:
+<pre>
+ B - Swatch Internet time
+ I (capital i) - "1" if Daylight Savings Time, "0" otherwise.
+ W - ISO-8601 week number of year, weeks starting on Monday
+
+</pre>
+
+
+** FUNCTION adodb_date2($fmt, $isoDateString = false)
+Same as adodb_date, but 2nd parameter accepts iso date, eg.
+
+ adodb_date2('d-M-Y H:i','2003-12-25 13:01:34');
+
+
+** FUNCTION adodb_gmdate($fmt, $timestamp = false)
+
+Convert a timestamp to a formatted GMT date. If $timestamp is not defined, the
+current timestamp is used. Unlike the function date(), it supports dates
+outside the 1901 to 2038 range.
+
+
+** FUNCTION adodb_mktime($hr, $min, $sec[, $month, $day, $year])
+
+Converts a local date to a unix timestamp. Unlike the function mktime(), it supports
+dates outside the 1901 to 2038 range. All parameters are optional.
+
+
+** FUNCTION adodb_gmmktime($hr, $min, $sec [, $month, $day, $year])
+
+Converts a gmt date to a unix timestamp. Unlike the function gmmktime(), it supports
+dates outside the 1901 to 2038 range. Differs from gmmktime() in that all parameters
+are currently compulsory.
+
+** FUNCTION adodb_gmstrftime($fmt, $timestamp = false)
+Convert a timestamp to a formatted GMT date.
+
+** FUNCTION adodb_strftime($fmt, $timestamp = false)
+
+Convert a timestamp to a formatted local date. Internally converts $fmt into
+adodb_date format, then echo result.
+
+For best results, you can define the local date format yourself. Define a global
+variable $ADODB_DATE_LOCALE which is an array, 1st element is date format using
+adodb_date syntax, and 2nd element is the time format, also in adodb_date syntax.
+
+ eg. $ADODB_DATE_LOCALE = array('d/m/Y','H:i:s');
+
+ Supported format codes:
+
+<pre>
+ %a - abbreviated weekday name according to the current locale
+ %A - full weekday name according to the current locale
+ %b - abbreviated month name according to the current locale
+ %B - full month name according to the current locale
+ %c - preferred date and time representation for the current locale
+ %d - day of the month as a decimal number (range 01 to 31)
+ %D - same as %m/%d/%y
+ %e - day of the month as a decimal number, a single digit is preceded by a space (range ' 1' to '31')
+ %h - same as %b
+ %H - hour as a decimal number using a 24-hour clock (range 00 to 23)
+ %I - hour as a decimal number using a 12-hour clock (range 01 to 12)
+ %m - month as a decimal number (range 01 to 12)
+ %M - minute as a decimal number
+ %n - newline character
+ %p - either `am' or `pm' according to the given time value, or the corresponding strings for the current locale
+ %r - time in a.m. and p.m. notation
+ %R - time in 24 hour notation
+ %S - second as a decimal number
+ %t - tab character
+ %T - current time, equal to %H:%M:%S
+ %x - preferred date representation for the current locale without the time
+ %X - preferred time representation for the current locale without the date
+ %y - year as a decimal number without a century (range 00 to 99)
+ %Y - year as a decimal number including the century
+ %Z - time zone or name or abbreviation
+ %% - a literal `%' character
+</pre>
+
+ Unsupported codes:
+<pre>
+ %C - century number (the year divided by 100 and truncated to an integer, range 00 to 99)
+ %g - like %G, but without the century.
+ %G - The 4-digit year corresponding to the ISO week number (see %V).
+ This has the same format and value as %Y, except that if the ISO week number belongs
+ to the previous or next year, that year is used instead.
+ %j - day of the year as a decimal number (range 001 to 366)
+ %u - weekday as a decimal number [1,7], with 1 representing Monday
+ %U - week number of the current year as a decimal number, starting
+ with the first Sunday as the first day of the first week
+ %V - The ISO 8601:1988 week number of the current year as a decimal number,
+ range 01 to 53, where week 1 is the first week that has at least 4 days in the
+ current year, and with Monday as the first day of the week. (Use %G or %g for
+ the year component that corresponds to the week number for the specified timestamp.)
+ %w - day of the week as a decimal, Sunday being 0
+ %W - week number of the current year as a decimal number, starting with the
+ first Monday as the first day of the first week
+</pre>

+NOTES
+
+Useful url for generating test timestamps:
+ http://www.4webhelp.net/us/timestamp.php
+
+Possible future optimizations include
+
+a. Using an algorithm similar to Plauger's in "The Standard C Library"
+(page 428, xttotm.c _Ttotm() function). Plauger's algorithm will not
+work outside 32-bit signed range, so i decided not to implement it.
+
+b. Implement daylight savings, which looks awfully complicated, see
+ http://webexhibits.org/daylightsaving/
+
+
+CHANGELOG
+- 16 Jan 2011 0.36
+Added adodb_time() which returns current time. If > 2038, will return as float
+
+- 7 Feb 2011 0.35
+Changed adodb_date to be symmetric with adodb_mktime. See $jan1_71. fix for bc.
+
+- 13 July 2010 0.34
+Changed adodb_get_gm_diff to use DateTimeZone().
+
+- 11 Feb 2008 0.33
+* Bug in 0.32 fix for hour handling. Fixed.
+
+- 1 Feb 2008 0.32
+* Now adodb_mktime(0,0,0,12+$m,20,2040) works properly.
+
+- 10 Jan 2008 0.31
+* Now adodb_mktime(0,0,0,24,1,2037) works correctly.
+
+- 15 July 2007 0.30
+Added PHP 5.2.0 compatability fixes.
+ * gmtime behaviour for 1970 has changed. We use the actual date if it is between 1970 to 2038 to get the
+ * timezone, otherwise we use the current year as the baseline to retrieve the timezone.
+ * Also the timezone's in php 5.2.* support historical data better, eg. if timezone today was +8, but
+ in 1970 it was +7:30, then php 5.2 return +7:30, while this library will use +8.
+ *
+
+- 19 March 2006 0.24
+Changed strftime() locale detection, because some locales prepend the day of week to the date when %c is used.
+
+- 10 Feb 2006 0.23
+PHP5 compat: when we detect PHP5, the RFC2822 format for gmt 0000hrs is changed from -0000 to +0000.
+ In PHP4, we will still use -0000 for 100% compat with PHP4.
+
+- 08 Sept 2005 0.22
+In adodb_date2(), $is_gmt not supported properly. Fixed.
+
+- 18 July 2005 0.21
+In PHP 4.3.11, the 'r' format has changed. Leading 0 in day is added. Changed for compat.
+Added support for negative months in adodb_mktime().
+
+- 24 Feb 2005 0.20
+Added limited strftime/gmstrftime support. x10 improvement in performance of adodb_date().
+
+- 21 Dec 2004 0.17
+In adodb_getdate(), the timestamp was accidentally converted to gmt when $is_gmt is false.
+Also adodb_mktime(0,0,0) did not work properly. Both fixed thx Mauro.
+
+- 17 Nov 2004 0.16
+Removed intval typecast in adodb_mktime() for secs, allowing:
+ adodb_mktime(0,0,0 + 2236672153,1,1,1934);
+Suggested by Ryan.
+
+- 18 July 2004 0.15
+All params in adodb_mktime were formerly compulsory. Now only the hour, min, secs is compulsory.
+This brings it more in line with mktime (still not identical).
+
+- 23 June 2004 0.14
+
+Allow you to define your own daylights savings function, adodb_daylight_sv.
+If the function is defined (somewhere in an include), then you can correct for daylights savings.
+
+In this example, we apply daylights savings in June or July, adding one hour. This is extremely
+unrealistic as it does not take into account time-zone, geographic location, current year.
+
+function adodb_daylight_sv(&$arr, $is_gmt)
+{
+ if ($is_gmt) return;
+ $m = $arr['mon'];
+ if ($m == 6 || $m == 7) $arr['hours'] += 1;
+}
+
+This is only called by adodb_date() and not by adodb_mktime().
+
+The format of $arr is
+Array (
+ [seconds] => 0
+ [minutes] => 0
+ [hours] => 0
+ [mday] => 1 # day of month, eg 1st day of the month
+ [mon] => 2 # month (eg. Feb)
+ [year] => 2102
+ [yday] => 31 # days in current year
+ [leap] => # true if leap year
+ [ndays] => 28 # no of days in current month
+ )
+
+
+- 28 Apr 2004 0.13
+Fixed adodb_date to properly support $is_gmt. Thx to Dimitar Angelov.
+
+- 20 Mar 2004 0.12
+Fixed month calculation error in adodb_date. 2102-June-01 appeared as 2102-May-32.
+
+- 26 Oct 2003 0.11
+Because of daylight savings problems (some systems apply daylight savings to
+January!!!), changed adodb_get_gmt_diff() to ignore daylight savings.
+
+- 9 Aug 2003 0.10
+Fixed bug with dates after 2038.
+See http://phplens.com/lens/lensforum/msgs.php?id=6980
+
+- 1 July 2003 0.09
+Added support for Q (Quarter).
+Added adodb_date2(), which accepts ISO date in 2nd param
+
+- 3 March 2003 0.08
+Added support for 'S' adodb_date() format char. Added constant ADODB_ALLOW_NEGATIVE_TS
+if you want PHP to handle negative timestamps between 1901 to 1969.
+
+- 27 Feb 2003 0.07
+All negative numbers handled by adodb now because of RH 7.3+ problems.
+See http://bugs.php.net/bug.php?id=20048&edit=2
+
+- 4 Feb 2003 0.06
+Fixed a typo, 1852 changed to 1582! This means that pre-1852 dates
+are now correctly handled.
+
+- 29 Jan 2003 0.05
+
+Leap year checking differs under Julian calendar (pre 1582). Also
+leap year code optimized by checking for most common case first.
+
+We also handle month overflow correctly in mktime (eg month set to 13).
+
+Day overflow for less than one month's days is supported.
+
+- 28 Jan 2003 0.04
+
+Gregorian correction handled. In PHP5, we might throw an error if
+mktime uses invalid dates around 5-14 Oct 1582. Released with ADOdb 3.10.
+Added limbo 5-14 Oct 1582 check, when we set to 15 Oct 1582.
+
+- 27 Jan 2003 0.03
+
+Fixed some more month problems due to gmt issues. Added constant ADODB_DATE_VERSION.
+Fixed calculation of days since start of year for <1970.
+
+- 27 Jan 2003 0.02
+
+Changed _adodb_getdate() to inline leap year checking for better performance.
+Fixed problem with time-zones west of GMT +0000.
+
+- 24 Jan 2003 0.01
+
+First implementation.
