PHP / Javascript clock problem

    I got some code that makes a clock that shows the time. if you choose a region it shows the time in that region. I am using PHP to get the server time to use as the base time. It works fine for me here in Japan, but if a user in Germany looks at the clock the time goes totally wrong. This is confusing because it is using the server time.

    Can anyone spot where the problem is?
