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.

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)
}
