Description:
------------
I do believe this issue is with date.  None of the bugs that appeared seemed to say the issue was resolved.  I will install latest cvs and see if that resolves the issue and then update the bug issue.

Reproduce code:
---------------
<?php
error_reporting(E_ALL);
for($x = 1; $x < 13; $x++ ){
echo date("F", jdtounix(GregorianToJD( $x, 1 ,2008 )))." - ".$x."<br />";
}
?>

Expected result:
----------------
January - 1
February - 2
March - 3
April - 4
May - 5
June - 6
July - 7
August - 8
September - 9
October - 10
November - 11
December - 12

Actual result:
--------------
December - 1
January - 2
February - 3
March - 4
April - 5
May - 6
June - 7
July - 8
August - 9
September - 10
October - 11
November - 12

Seems to be an issue on how the functions return the timestamp.  I don't think this is the issue as it takes up to 15 days, and not the difference of GMT vs local time, to make the proper month output.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

You need to add date_default_timezone_set('UTC'); to your 
code. Otherwise the timezone changes jan 1 to Dec 31.

Thanks, I spent a few hours trying to figure this out...  Someone already told me it's not a bug.

I did try changing the day to the 15th and that didn't make a difference.
