Description:
------------
jdtounix and unixtojd conversions are 1 day out when timezones are in effect. Specifically, when timezone is negative GMT.

This is happening on both WinXP and Linux for PHP4.3.4 and 4.3.6.

On Windows, it's even more weird. time() returns the 1 May 2004 not 2 May 2004. 


Reproduce code:
---------------
See test script at http://dev.worlddo.com/jdtime.php

Expected result:
----------------
Test script produces both expected and actual results for comparison

On the dev.worlddo.com script, try anything -GMT, e.g. America/Denver or even Atlantic/Cape Verde. You'll see that the strftime() returns 04/30/2004 NOT 05/01/2004.

On Windows, try Australia/Brisbane. The time is out by 2 hours - 5/2/2004 12:27:59 AM  instead of 5/2/2004 10:27.59 AM.

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

Not a bug as Julian Days start at noon, not at midnight, if you shift to 13:00 you\'ll see that it works fine.
