countdown 5 minutes at each login allow kid to spend more time

[nicopiot]

Hello,
I just installed kidtimer, it works pretty well, and I made a suggestion in the pull request.
The only problem I found is than when the time is finished, my kid can login again, and she will get another 5 minutes of countdown that she can use. She has done it 5 times this morning which gave her 25 more minutes than allowed.
and the user.ttl file was negative -27.
Is there a way to logout straight away if say the user.ttl file is below 5.
maybe a script file that we manually add in the user $HOME/.bash_profile? sorry if I say stupid things, I am not a programmer at all and also quite new in linux.

Anyway, if someone has a simple fix for that, I would appreciate.

thanks
