child monitoring tool?

Hello,

I'm a father of two.

My children are always having an argue about the computer.
They never seem to tell the truth about the ammount of time they spent on playing computer games. So my daughter tells my son that it's her turn now and my son tells my daughter so.

I was wondering, is there a program for parents which will monitor the ammount of time spent on the PC by an individual user.

For example when you start up the computer, you need to use your own account to acces and then the program tells me the ammount of time spent on the account of my daughter or son.


So that everyone has it's own account with his own password and that I can see the ammount of time as an admin.

thanks in advance

 

well thanks for the help man.

But I thought about something more easier.

I only want a proggie for a timetable, I myself don't mind how long they sit on.
Just to log the time for every user. No restrictions or something, so there's evidence when one has been playing twice as much as the other one.

Is there a program like this, small freeware, no extended features and hard to bypass. Thanks

 

anyone?
