How to disable the "Daylight saving time" in PHP 5?

I need to disable the "Daylight saving time" in PHP 5. My servers (Windows, both XP and Vista) have correct local time but PHP 5 adds an extra hour when I use date("H") or other time functions. Instead of getting 9 AM, I get 10 AM. If I run date("I"), I get 1, which confirms that PHP 5 is using "Daylight saving time". If I change the system date to January I get correct hour. I have tried google.com and I ran through the php.net manual but I didn't find a solution. I cannot add time-fix on every php-page, they are to many.
