Description:
------------
getdate function returns wrong "weekday" for higher negative timestamps like  -12.3456789000e10. This is observed on linux 64 bit with both php5.2 and php5.3 release. 

As per documentation "weekday" should be "Sunday through Saturday".
But in this case it returns "Unknown" value.

Checked with php version
PHP 5.3.0alpha3-dev (cli) (built: Oct 29 2008 15:20:01)



Reproduce code:
---------------
<?php
$timestamp=-12.3456789000e10;
var_dump( getdate($timestamp) );
?>


Expected result:
----------------
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) "Monday"
  ["month"]=>
  string(7) "October"
  [0]=>
  int(-123456789000)
}


Actual result:
--------------
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"
  ["month"]=>
  string(7) "October"
  [0]=>
  int(-123456789000)
}

I found the bug, and have a fix... but was wondering why you think it should be a Monday. I calculate it as a Wednesday.
