With cryptic overly specific tasks and one that ends up being the 'catch all' for everything that doesn't fit one of the narrow categories?

40 hours a week spent on "General and Administrative". All 40 hours spent in the system, entering the 40 hours, thus the timecode is correct.

You should see law firm timekeeping. It can be mind-blowingly labyrinthine.

I used to enter 15-30 minutes a day on my timesheets for doing timesheets. It was honest but felt rebellious.

This is the only way to go. If these numbers are ever actually used for something, maybe somebody will realize that the timesheets system can be improved.
