Description:
------------
Cascading
unixtojd and jdtounix
does not produce the original input.

Reproduce code:
---------------
jdtounix(unixtojd(1198450800))



Expected result:
----------------
since these are inverse functions, one would expect
an unchanged result, independantly of localtime and daylightsaving issues:
1198450800

Actual result:
--------------
1198454400
which is one hour offsetresults in:
1198454400
which is one hour offset.

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

\"The time returned is localtime (and not GMT).\" http://php.net/jdtounix
Whereas unixtojd assumes GMT timestamps, unfortunate, but changing it would create problems for people who rely on this behavior.
