I worked in a desktop support environment where we "charged" for our onsite time and then were forced to track all the rest of our time at work too. I use quote marks around charged because it was all internal dollars with in the larger organization.

After about 3 months of it all the staff basically revolted and demanded that the requirement of entering everything into the tracking system be halted. All the analysis had shown was that we were all spending nearly 1/4 of our day tracking what we were doing in the other 3/4's of the day.
