plesk time settings corrupt

[ps4you]

I have the following problem. I have a Centos 4.3 box. When i set the Time zone with the tool system-config-date to Europe vienna with UTC set plesk the setting to Europe Vienna CEST (GMT +00:00) CEST - UTC is the system setting but it is ignored. The default setting for Europe Vienna is (GMT +02:00) in plesk view (GMT +00:00). When i set the Time zone to Europe Berlin is it the same Problem. I think it is a problem with the system setting and the plesk settings. How can i disable the plesk Time zone or restore it.

Best regards Wolfgang
