just wanted to post a quick note about this, originally it was supposed to finish on 16th march but it has being extended to 3rd April.
if your php script is giving you one hour late time then here is the solution

you might need to compile it for your system, alternatively you can also update the php to it’s latest release.
here is the link if you need more info http://pecl.php.net/bugs/bug.php?id=12151 .
