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:
+
+
+ %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
+
+
+ Unsupported codes:
+
+ %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

CHANGELOG
+
+- 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.
