If you read this article there was clear admission of lying about logging hours by the employee. However, that aside I think software to track productivity is pretty garbage way in a lot of jobs to keep track of employees. Example, I do a ton of research as part of my job and often that's reading from books, or looking up things in hardcopy form that didn't come from my laptop. Also I do a fair amount of design or planning on a white board I keep next to my desk. Often my computer goes to sleep in those times but I'm definitely still working. Production metrics are way better measures of work than raw time in an application.
