I have asked this question in
security.stackexchange.com, but I was unable to get anything useful. So I am re-posting it here.
In parental control I can restrict the games, applications, and also set time for usage. But how can I grant some privilege (like using some application or playing games) with validity period? To be more specific, I have parental control set to an user account with all games blocked, again if I grant access to play games, it should be valid only up-to the time that I specify, and when the time expires it should roll-back to all games blocked stage.
How can I do this? Do I need any other software to do this?
