Where can we send feedback about errors found in localization of strftime output?
Romanian words are very buggy (e.g. SîmbĂtĂ should be Sâmbătă and many others...)
strftime
(PHP 4, PHP 5)
strftime — 根据区域设置格式化本地时间／日期
说明
string strftime
( string $format
[, int $timestamp
] )
返回用给定的格式字串对给出的 timestamp 进行格式输出后的字符串。如果没有给出时间戳则用当前的本地时间。月份和星期几以及其它和语言有关的字符串写法和用 setlocale() 设定的当前的区域有关。
格式字串能识别下列转换标记：
- %a - 当前区域星期几的简写
- %A - 当前区域星期几的全称
- %b - 当前区域月份的简写
- %B - 当前区域月份的全称
- %c - 当前区域首选的日期时间表达
- %C - 世纪值（年份除以 100 后取整，范围从 00 到 99）
- %d - 月份中的第几天，十进制数字（范围从 01 到 31）
- %D - 和 %m/%d/%y 一样
- %e - 月份中的第几天，十进制数字，一位的数字前会加上一个空格（范围从 ' 1' 到 '31'）
- %g - 和 %G 一样，但是没有世纪
- %G - 4 位数的年份，符合 ISO 星期数（参见 %V）。和 %V 的格式和值一样，只除了如果 ISO 星期数属于前一年或者后一年，则使用那一年。
- %h - 和 %b 一样
- %H - 24 小时制的十进制小时数（范围从 00 到 23）
- %I - 12 小时制的十进制小时数（范围从 00 到 12）
- %j - 年份中的第几天，十进制数（范围从 001 到 366）
- %m - 十进制月份（范围从 01 到 12）
- %M - 十进制分钟数
- %n - 换行符
- %p - 根据给定的时间值为 `am' 或 `pm'，或者当前区域设置中的相应字符串
- %r - 用 a.m. 和 p.m. 符号的时间
- %R - 24 小时符号的时间
- %S - 十进制秒数
- %t - 制表符
- %T - 当前时间，和 %H:%M:%S 一样
-
%u - 星期几的十进制数表达 [1,7]，1 表示星期一
Warning
尽管 ISO 9889:1999（当前的 C 标准）明确指出一周从星期一开始，但是 Sun Solaris 的一周似乎从星期天开始并作为 1。
- %U - 本年的第几周，从第一周的第一个星期天作为第一天开始
- %V - 本年第几周的 ISO 8601:1988 格式，范围从 01 到 53，第 1 周是本年第一个至少还有 4 天的星期，星期一作为每周的第一天。（用 %G 或者 %g 作为指定时间戳相应周数的年份组成。）
- %W - 本年的第几周数，从第一周的第一个星期一作为第一天开始
- %w - 星期中的第几天，星期天为 0
- %x - 当前区域首选的时间表示法，不包括时间
- %X - 当前区域首选的时间表示法，不包括日期
- %y - 没有世纪数的十进制年份（范围从 00 到 99）
- %Y - 包括世纪数的十进制年份
- %Z 或 %z - 时区名或缩写
- %% - 文字上的 `%' 字符
Note: 可能不是所有的转换标记都被 C 库文件支持，这种情况下 PHP 的 strftime() 也不支持。此外，不是所有的平台都支持负的时间戳，因此日期的范围可能限定在不早于 Unix 纪元。这意味着例如 %e, %T，%R 和 %D（可能更多）以及早于 Jan 1, 1970 的时间在 Windows，一些 Linux 发行版本，以及其它几个操作系统中无效。对于 Windows 系统，所支持的转换标记可在 » MSDN 网站找到。
Example#1 strftime() 区域的例子
<?php
setlocale(LC_TIME, "C");
echo strftime("%A");
setlocale(LC_TIME, "fi_FI");
echo strftime(" in Finnish is %A,");
setlocale(LC_TIME, "fr_FR");
echo strftime(" in French %A and");
setlocale(LC_TIME, "de_DE");
echo strftime(" in German %A.\n");
?>
Note: %G 和 %V，如果数字编号系统未能充分理解，基于 ISO 8601:1988 的星期数可能得出未预期的结果。见上面的 %V 和以下的例子。

Fetch a timestamp or datetime of a given week can be accomplished very easy...
/**
* Get the start of a given week (in this case monday is first day = W)
*
* @param integer $iWeekNumber
* @param integer $iYear
* @param string $sFormat
* @return mixed Datetime or UNIX time depending on format
*/
function getDatetimeWeekStart( $iWeekNumber, $iYear, $sFormat = 'd\.m\.Y' )
{
$iWeekNumber = sprintf("%02s", $iWeekNumber);
$iTime = strtotime($iYear.'W'.$iWeekNumber);
return date($sFormat, $iTime);
}
Example this week:
print getDatetimeWeekStart(date('W'));
Example week 10 in 2006:
print getDatetimeWeekStart(10, 2006);
Example week 52 in 2009 in unixtime:
print getDatetimeWeekStart(52, 2009, 'U');

Here's a simple version for date formating i use between displaying in HTML and converting back to MYSQL format:
function format_date($original='', $format="%m/%d/%Y") {
$format = ($format=='date' ? "%m-%d-%Y" : $format);
$format = ($format=='datetime' ? "%m-%d-%Y %H:%M:%S" : $format);
$format = ($format=='mysql-date' ? "%Y-%m-%d" : $format);
$format = ($format=='mysql-datetime' ? "%Y-%m-%d %H:%M:%S" : $format);
return (!empty($original) ? strftime($format, strtotime($original)) : "" );
}
example (in HTML or webapp):
[grab from database]...
$dbase_stored_date = "2007-03-15";
$display_html_date = format_date($dbase_stored_date);
... displays as "03/15/2007"
example (saving form via on POST/GET):
$update_date = format_date($_POST['display_html_date'], 'mysql-date');
// converts back to '2007-03-15'
.... [your mysql update here]
Don't forget to sanitize your POST/GET's =)

If the second parameter is null, PHP treats it as 0, so strftime return something like 01/01/1970. Be aware of this.

Here is a function to convert dates before 1970, very useful if you are still using php 4 (it is supported in php5) :
# convert a date to special format
# $date is like 2000-01-01 00:00:00
# $format : refer to strftime function
function convert_date($date,$format) {
if($date=='0000-00-00 00:00:00' OR $date=='0000-00-00' OR $date=='' OR $date==NULL) {
return '';
}
else {
$year=substr($date,0,4);
if(phpversion() < 5.0 AND $year < 1970) {
$new_date=substr_replace($date,'1980',0,4); # we replace the year by a year after 1970
$new_format=eregi_replace('%a|%A|%u','',$format); # we remove days information from the format because they would be wrong
$new_date=strftime($new_format,strtotime($new_date)); # we convert the date
$new_date=eregi_replace('1980',$year,$new_date); # we put back the real year
return $new_date;
}
else {
return strftime($format,strtotime($date));
}
}
}

note, that for some languages you MUST set LC_ALL instead of LC_TIME.
note that you further have to explicitly define your output-encoding (default is ISO-8859-1 [which makes problems for some languages])!
at least i expirienced this behaviour on a german WinXP-PHP4 environment:
<?php
// does not work - gives question marks:
setlocale(LC_TIME, 'RUS'); // ISO Alpha-3 is supported by xp
echo strftime('%A', time());
?>
<?php
// DOES work:
header('Content-Type: text/html; charset=UTF-8'); // you could also use another charset here if iconv isn't installed on your system.
echo setlocale(LC_ALL, 'RUS').': ';
echo iconv('windows-1251', 'UTF-8', strftime('%A', time()))."\n";

This little function allows you to provide a reasonably human readable string and convert to a timestamp - see example in comments below.
I find it far more useful than having to remember all the '%' modifiers. Am also well aware of its failings but it works in a lot of the real life situations I've come across.
<?php
function AmazingStringFromTime($str, $nTimestamp = null)
{
// This function reads a human readable string representation of dates. e.g.
// DD MM YYYY => 01 07 1978
// DDD D MMM YY => Mon 1 Jul 78
$arrPairs = array(
"DDDD" => "%A",
"DDD" => "%a",
"DD" => "%d",
"D" => "%e", // has leading space: ' 1', ' 2', etc for single digit days
"MMMM" => "%B",
"MMM" => "%b",
"MM" => "%m",
"YYYY" => "%Y",
"YY" => "%y",
"HH" => "%H",
"hh" => "%I",
"mm" => "%M",
"ss" => "%S",
);
$str = str_replace(array_keys($arrPairs), array_values($arrPairs), $str);
return strftime($str, $nTimestamp);
}

Security notice:
You can end with a (probably unexpected) XSS if the $format parameter is user submitted data ;)
<?php

Function strftime() use the locales installed in your system (linux).
If you are like me and only leave in the system the locales you use normally (en_US and your own language locale, like es_ES), you'll only be able to use the locales installed. If your application is translated to other languages, you need these locales too.
The name of the locale in your system is important too. This can be a problem when you want to distribute the app.
If you have this locales in your system:
en_US/ISO-8859-1
en_US.UTF-8/UTF-8
es_ES/ISO-8859-1
es_ES@euro/ISO-8859-15
es_ES.UTF-8/UTF-8
es_ES@euro/UTF-8
and use setlocale('es_ES'), the result will use the iso-8859-1 charset even if you have all your system, files and configuration options in UTF-8. To receive content in UTF-8, in this example, you need to use setlocale('es_ES.UTF-8') or setlocale('es_ES.UTF-8@UTF-8').
The definition of locales can change from one system to another, and so the charset from the results.

Thats how I get the %G, %g ISO Year and %V Week with php 4.4.4 on Window$.
It works quite simple:
1. on January it can't be a week bigger than 51, thats what i've learned in school
2. on december many weeks have gone since the last New Year's Eve and therefore it cant be the first week of the year
i hope it saves time
<?php
function YearOfWeek($format,$date = NULL){
if(!isset($date)){
$date = time();
}
list ($G,$V,$month) = explode('_',date ('Y_W_m',$date));
if( ($month === '01') && ($V >= 52 ) ){
$G--;
}else if( ($month === '12') && ($V === '01') ){
$G++;
}
$g = substr($G, -2, 2);
$format = str_replace(array('%V','%G','%g'),array($V,$G,$g),$format);
return ($format);
}
$format = 'week %V of the year %G (%g), year %Y (%y)';
$date = mktime(0, 0, 0, 12, 31, 2008);
//week 01 of the year 2009 (09), year 2008 (08)
echo strftime(YearOfWeek($format,$date), $date) . "\n";
$date = mktime(0, 0, 0, 1, 1, 2010);
//week 53 of the year 2009 (09), year 2010 (10)
echo strftime(YearOfWeek($format,$date), $date) . "\n";
echo strftime(YearOfWeek($format)) . "\n";
//something like: week 51 of the year 2006 (06), year 2006 (06)
//depends on the day you do this

(in addition to Andy's post)
To get a RFC 2822 date (used in RSS) of the current local time :
echo strftime ("%a, %d %b %Y %H:%M:%S %z") ;
Note: option %z / %Z - work different on Windows platform, for example
output of this code line can be:
Thu, 02 Nov 2006 09:54:59 Jerusalem Standard Time (on Windows)
Thu, 02 Nov 2006 09:54:59 +0200 (on Linux)

Your point about javascript not being universal is correct. However, accept language header does not tell you the local time difference, which is the essential problem.
Also, as you point out, accept language is also not universal.
Most browsers do accept javascript. it is in common use by many websites. It is a safe bet if you are using drop down menus for instance that the script will work, otherwise they would not be able to use your site at all.

@NicSoft: And what if the user's browser doesn't support JavaScript? You should either use the possibilities offered by PHP (most browsers send an Accept-Language header, from where you can extract the language to use) or at least offer the english name (e.g. inside <noscript>)

A simple work around for displaying dates in local format is to get the browser to do it for you using javascript.
This routine accepts a date time field from sql,
and gets the timezone offset for your server, and passes these over to the browser in the form of a javascript script.
Javascript calculates the time difference and uses toLocaleString to display it.
function DisplaySQLDateInLocalTime($SQLDate){
list($year,$mon,$day,$hour,$min,$sec)=split('[-: ]',$SQLDate);
$TimeZoneOffset=date('Z') /60;
$JS="\n<script><!--\n";
$JS.="LocalTime = new Date();\n";
$JS.="TimeZoneOffsetInMins = LocalTime.getTimezoneOffset();\n";
$JS.="ServerTimeZoneOffset=$TimeZoneOffset;\n";
$JS.="timediff=-TimeZoneOffsetInMins - ServerTimeZoneOffset;\n";
$JS.="LocalTime = new Date(".$year.","
.($mon-1).",".$day.",".$hour.",".$min.",".$sec.");\n";
$JS.="DateVal=LocalTime.valueOf();\n";
$JS.="LocalTime=new Date(DateVal+timediff*1000*60);\n";
$JS.="document.write( LocalTime.toLocaleString());\n";
$JS.="//--></script>\n";
return $JS;

In response to the note supplied by "Arpad Borsos":
I think the whole truth is that the output of strftime() considers whatever you stated with setlocale().
<?php
/* Berlin is in Germany */
$locale = setlocale (LC_ALL, 'de_DE.UTF-8');
/* Output: Donnerstag, 23. März 2006 (and hopefully UTF-8 ;) */
echo strftime ("%A, %d. %B %Y", strtotime('2006-03-23'));
/* try different possible locale names for german as of PHP 4.3.0 */
$locale = setlocale(LC_ALL, 'de_DE.UTF-8', 'de_DE.UTF-8@euro', 'de_DE');
echo "Preferred locale for german on this system is '$locale'";
?>
Check the documentation of setlocale() for more.
setlocale (LC_ALL, 'de_DE.UTF-8') always worked fine for me.

Please note that the strftime output is not encoded in utf8 so you have to use utf8_encode() if you want to print localized month names e.g. for German "März"
[red. this depends on the platform though - some Windows locales *do* use UTF-8 for example]

To mcallister, phloe and anyone else who want to get on the getDaySuffix() band wagon:
There are already functions to do this. All you really have to do is:
<?=date("jS", mktime(0,0,0,1,$myDay,2006))?>
Obviously, the only part of mktime that really matters is $myDay.

In response to the note supplied by "segfault nycap rr com".
Here is a quicker and easier way:
Use the MySQL Time Function TIME_FORMAT() in your query:
mysql> SELECT TIME_FORMAT('14:35:00', '%l:%i %p');
Or try '%l' in PHP, it works on most systems and is part of the Open Group specification of strftime().
<?php
echo strftime('%l:%M %p', strtotime('14:35:00'));

When using strftime to generate time stamps for inclusion in RSS feeds, be sure to use %z for the timezone (RFC-822 format) rather than %Z -- for some reason, %Z fails to validate.

To partialy correct Neo's on RFC 850 date...
RFC 850 is obsolete by RFC 1036.
In HTTP header, RFC 1123 is the first choice: it has a fixed length format and 4 digits year.
Therefore, the correct format is:
gmstrftime ("%a, %d %b %Y %T %Z", time ());
Output example: Sun, 06 Nov 1994 08:49:37 GMT
[red. Use date(DATE_RFC850, time()); instead. (Or DATE_RFC1123 or DATE_RFC1036)]

Under windows if you are using Japanese version, you must use the following code:
setlocale(LC_ALL, "Japanese_Japan.20932") for EUC
setlocale(LC_ALL, "Japanese_Japan.932") for SJIS

To correct an error in the above list of formatting codes:
%p - either `AM' or `PM' according to the given time value, or the corresponding strings for the current locale (note result is in capitals)
%P - either `am' or `pm' according to the given time value, or the corresponding strings for the current locale (note result is in lower case)
In addition, the following codes seem to return a value on my system (Linux, Apache/1.3.33, PHP/4.4.1), but are not documented above. I have included the result given by passing them to gmstrftime() with a timestamp of 0 (unix epoch). gmstrftime() was used to avoid timezone/DST differences.
%F: "1970-01-01" (appears to be an SQL-formatted version of the date)
%k: "0" (seems to be the hour in 24-hour clock, without leading zeros (space-padded))
%l: "12" (seems to be the hour in 12-hour clock, without leading zeros (space-padded))
%s: "-3600"
%s seems to be the Unix timestamp passed to the function, but somehow based on the current locale/TZ settings (even in gmstrftime()).
On my system strftime("%H:%M:%S", 0) returns "01:00:00", and strftime("%s", 0) returns "0". Using gmstrftime() I get "00:00:00" and "-3600" respectively.

This function is useful for news posts.
It displays the creation date and elapsed time like:
Sunday, December 4, 2005 - 2 days ago
Monday, December 5, 2005 - Yesterday
Monday, November 28, 2005 - 1 week ago
Friday, October 28, 2005 - 6 weeks ago
function off($date){
$date = strtotime($date);
$offset = (strftime("%j")+strftime("%Y")*365)-
(strftime("%j",$date)+strftime("%Y",$date)*365);
if ($offset>7){
$offset = (strftime("%V")+strftime("%Y")*52)-
(strftime("%V",$date)+strftime("%Y",$date)*52);
$end=($offset!=0?($offset>1?$offset . " weeks ago":"a week ago"):"Today");
} else
$end=($offset!=0?($offset>1?"$offset days ago":"Yesterday"):"Today");
return strftime("%A, %B %e, %Y",$date)." - ". $end;
}
To insert the time:
<?=off("12/4/05")?>

The following function implements the conversion specifiers which are not supported on Win32 platforms:
(Note: the specifiers %V, %G and %g can be implemented using other functions described in this section)
<?php
function strftime_win32($format, $ts = null) {
if (!$ts) $ts = time();
$mapping = array(
'%C' => sprintf("%02d", date("Y", $ts) / 100),
'%D' => '%m/%d/%y',
'%e' => sprintf("%' 2d", date("j", $ts)),
'%h' => '%b',
'%n' => "\n",
'%r' => date("h:i:s", $ts) . " %p",
'%R' => date("H:i", $ts),
'%t' => "\t",
'%T' => '%H:%M:%S',
'%u' => ($w = date("w", $ts)) ? $w : 7
);
$format = str_replace(
array_keys($mapping),
array_values($mapping),
$format
);
return strftime($format, $ts);
}
?>

For freebsd user:
You can find the full list of your locale under /usr/share/locale.
For example da_DK.ISO8859-1 under this directory will set up the locale to danish.

i had to use the czech representation of time on unix machine, running debian and linux version of apache with php 4
for me the best solution was to use this code:
<php
setlocale(LC_ALL, 'cs_CZ.iso88592');
?>
then you can do everything in czech language with correct iso-8859-2 encoding ;D

%k will give you %H (hour, 24-hour clock) with the leading zero replaced by a space. I have only tested this on one linux system so far, it may not work on windows or other linux builds.

As said in these comments, Windows strftime() doesn't support %e. However, to achieve a similar effect (not 100%) you can use %#d. The # flag will remove the leading zero, so you do get single digits, but without the space that would be added by %e in other environments.

To get a RFC 850 date (used in HTTP) of the current time:
gmstrftime ("%A %d-%b-%y %T %Z", time ());
This will get for example:
Friday 25-Jun-04 03:30:23 GMT
Please note that times in HTTP-headers _must_ be GMT, so use gmstrftime() instead of strftime().

In the strftime override-function of rickenmeer at hotmail dot com there is an error.
The line:
$year = 1969;
should read:
$year = 1970;

Searching for translation from IBASE-Timestamp to EU-Dateformat DD.MM.YYYY
strftime("%d.%m.%Y",strtotime($row->START_TIMESTAMP));
Maybe it's useful for somebody ;-)

Note that setting LC_TIME is not enough for some locales under Windows, e.g. Czech, because there are some characters not contained in default (US) character set like '' (c with hook), '' (r with hook).
If you run Apache as regular application and have set your locale to Czech (ControlPanel/RegionalOptions), there is no problem and 'September' is correctly translated as 'z', 'Thursday' as 'tvrtek'.
But if you run Apache as service, you get 'zr', and 'ctvrtek'.
To get things work as you expect you must set LC_CTYPE beside LC_TIME, or set LC_ALL.
<?
$locale = 'Czech_Czech.1250';
$res = setlocale( 'LC_CTYPE', $locale); //important
$res = setlocale( 'LC_TIME', $locale);
echo strftime( '%A %m. %B %Y', mktime( 0,0,0,9,6,2001));
?>

Beware of '%D':
the comment shown expects that this is the same as '%m/%d/%y'.
This is wrong: '%D' is only expected to returned an abbreviated numeric date according to the current locale:
In the German locale '%D' is '%y.%m.%d'
In the French locale '%D' is '%d/%m/%y'
The locale rules still apply to %D as with '%A'...
Beware that some C libraries do not support '%D' and/or '%A' or do not support them accordingly. Using strftime() is then system-dependant, because PHP use the C function provided by the system on which it runs.

Solaris 2.6 and 7 define the
%u specifier differently than noted here. Day 1 is Sunday, not Monday. Solaris 8 gets it right.

Locale names are OS dependent. HP-UX 11.0, for example, has three
German locales, de_DE.roman8, de_DE.iso88591, and
de_DE.iso885915@euro.
The command locale -a will display all available locales on a system.
So on HP-UX, to get German dates:
setlocale("LC_TIME", "de_DE.roman8");
print(strftime("%A\n"));
