script to log power on and poweroff

[Carlos Becker]

Hello,

For time tracking I need a script that simply logs 
the time when I switch on my computer and when I switch it off again.

I am using this script /etc/init/logmytime.conf

               
description     "logmytime"

start on runlevel [0623]

post-start script
        date >> /home/me/logmytime.log
end script

But this is only logging when I start my PC,
shutdown is not logged. I suspect that probably
the filesystem is allready unmountet when the script runs on shutdown.

How can I do it right ?

Thanks
Carlos
