The problem is that timesheets are answering the wrong question for you. You want to know whether your employees are working or goofing off, and you want to know how long projects take. You should be able to tell that from the results of the project, not the hours. If you have two employees, one of whom works great only in short bursts after long games of ping-pong, and another that works slowly and steadily, and they both finish identical projects in two days, your business only needs to know that projects like that will take two days. If you then ask the employees to enter timesheets, you'll lose goodwill of the ping-pong player for no good reason.
