gmstrftime

(PHP 4, PHP 5)

gmstrftime — Formátuje datum/čas v GMT/UTC vzhledem k národnímu nastavení

Popis

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

Chová se stejně jako strftime(), avšak vrácený čas je v Greenwich Mean Time (GMT). Například při spuštění v čase EST (východní standardní čas, GMT -0500) vypíše první níže uvedený řádek "Dec 31 1998 20:00:00", zatímco druhý "Jan 01 1999 01:00:00".

Příklad 332. gmstrftime() example


<?php

setlocale (LC_TIME, 'en_US');

echo strftime ("%b %d %Y %H:%M:%S", mktime (20,0,0,12,31,98))."\n";

echo gmstrftime ("%b %d %Y %H:%M:%S", mktime (20,0,0,12,31,98))."\n";

?>

Viz také strftime().

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().
