I also got this. Standard installation of Ubuntu 12.04. The file is indeed only created on shutdown. I logged in and out but the file wasn't there. Once I shut down my cumputer and started it again it was there. The timestamp matches exactly the shutdown time. (I waited a few minutes before starting it again.)
