Thank you for your time and sorry I could not post early, but was out of town.
The problem is somewhere with date/time and time zone setings in xoops. In general preferences my setings for server are GMT+2 and for default GMT+2. When I write new news at lets say 14:10PM and I set the time of publish to 14:10PM too, I also set no expire, approve and publish to home. Then I can see the news in admin menu as automated article with correct time of publish, but I can not see it in the news. In 2 hours the news is online. So I think there is some calculations related to time and time zone and there is the problem. System clock for both werkstation and server are GMT+2.
Thanks
Stefan
