gmstrftime

(PHP 4, PHP 5)

gmstrftime — Format a GMT/UTC time/date according to locale settings

설명

string gmstrftime ( string $format [, int $timestamp = time() ] )

Behaves the same as strftime() except that the time returned is Greenwich Mean Time (GMT). For example, when run in Eastern Standard Time (GMT -0500), the first line below prints "Dec 31 1998 20:00:00", while the second prints "Jan 01 1999 01:00:00".

인수

format: See description in strftime().
timestamp: 선택적인 timestamp 인수는 timestamp가 주어지지 않았을 경우, 현재 로컬 시간을 기본값으로 가지는 integer 유닉스 타임스탬프입니다. 즉, 기본값은 time() 값입니다.

반환값

Returns a string formatted according to the given format string using the given timestamp or the current local time if no timestamp is given. Month and weekday names and other language dependent strings respect the current locale set with setlocale().

If you want the dutch time on your pages and you are hosted on a server in the USA you can easily change it this way:





<?php


setlocale(LC_TIME, 'nl_NL');


$tgl = gmstrftime("%d %B %Y - %H:%M uur",time()+3600);


?>





Then use $tgl to display the right time.


Note the +3600 is a day light savings time correction.


The result: 22 maart 2005 - 16:39 uur





First I used the normal date function and this was the previous result: March 22, 2005 - 04:28 AM





I needed it for a dutch guestbook.





I'm new to PHP and it took me a while to find it out and maybe it's of no use for experienced PHP programmers but I thought people can always ignore my post :)

gmstrftime() should not be used to generate a RFC 850 date for use in HTTP headers, since its output is affected by setlocale().



Use gmdate instead:



gmdate('D, d M Y H:i:s') . ' GMT';

HTTP 1.1 (RFC 2068) requires an RFC 1123 date with a four digit year, so the correct format to use for a Last-modified header would look something like this:



<?php

header("Last-modified: " . 

gmstrftime("%a, %d %b %Y %T %Z",getlastmod()));

?>

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().
