At a place I once worked, we used to have an online timesheet we had to fill in, to show how we had spent our work time, with a whole series of different codes representing time spent on different areas (granularity of 15min logged).
This made for quite an overhead (tracking time spent in excessive detail & filling it in via the online logging system) - unsurprisingly one of the first things the timesheet team had to do was a provide a code for time spent (wasted would be more accurate) in timesheet related activities!
After a while, the timesheet system died a death as it was noticed how much time was spent on timesheet related activities rather than productive tasks
