I'm jealous; my current job is billed by the hour, so I have to be able to describe every hour I've worked. Mind you that's usually a fixed 8 hour / day logged on project X, so having to write them down isn't a problem. But I can't go home early without feeling guilt; I mean I can, but that also means I have to do overtime sometime else in the month, to make sure the hours all check out at the end of the month.
