If time management is something that eludes you, or if you simply want a better understanding of how you spend time on your computer, then RescueTime may be the tool for you. RescueTime is an online service that collates statistics when you are at your computer, displaying the results on an intuitive and private dashboard. The requisite data is automatically uploaded via an unobtrusive app available in Windows and Mac. I've been a paying user for over a month now, and have gained new insight into the amount of time I spend on tasks such as email, writing and social networking. A 14-day trial is available, as well as a completely free version of the service.
