ADOdb Date Library, part of the ADOdb abstraction library |
Download: http://phplens.com/phpeverywhere/ |
|
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_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 |
- 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 |
|
