Need for you the kchildlock application! The kchildlock is a tool to monitor and restrict the time a children spends on the computer. The limits can be specified per day of the week, by lower and upper hour limits, maximum daily usage time, and maximum weekly usage time. The same restriction limits can be applied to applications based on the user login. It requires the blackPanther OS with KDE4 Desktop.
