wrong time stamp in log filewrong time stamp in log file

[Struzik Wojciech <bm9ib2r5@xxxxxxxxx>]

I have updated a php to version 5.2.11. the timestamp in php log is
incorrect. the time differs from local time with 2 hours. In changelog
I can find the following information:
Updated timezone database to version 2009.13 (2009m) (Derick)
Is it related with my problem ???

When I run the following script:
<?php
print date('d M Y, H:i');
?>
It's returns a correct time.

I appreciate any help
