How to stop child from changing time on Android device

Norton Family seems to have a significant flaw in its curfew controls.  Child can simply change the device time.  I have read other posts and they highlight that you get a notification in the log files, but this is not useful.  Can I at least get an immediate email if the time is changed?  One of your competitors, Qustodio, handles this by allowing the parent to lock out control of the settings.  Is this an option with Norton Family?
