## #41542 — Sanjay Mantoor — 2008-10-29T04:53:11+00:00

Hello,

While I was working on getdate function, found different behavior with
respect to http://in.php.net/manual/en/function.getdate.php
This is observed only on linux 64bit.
Here is code
<?php
       $timestamp = -12.3456789000e10;
       var_dump( getdate($timestamp) );
?>

As per documentation weekday should be Sunday through Saturday but I
got "Unknown".
Here is the output:
array(11) {
 ["seconds"]=>
 int(20)
 ["minutes"]=>
 int(23)
 ["hours"]=>
 int(5)
 ["mday"]=>
 int(23)
 ["wday"]=>
 int(-4)
 ["mon"]=>
 int(10)
 ["year"]=>
 int(-1943)
 ["yday"]=>
 int(295)
 ["weekday"]=>
 string(7) "Unknown"     ====> It should be Sunday through Saturday
 ["month"]=>
 string(7) "October"
 [0]=>
 int(-123456789000)
}

Can somebody point-out what is the problem? And whether it is an
expected behavior.

It's a bug in the day-of-week algorithm in case there is a negative 
year. Could you file a bug please?
