Track task times in your Google Calendar with a Gadget
The gCalTasks gadget is a slick desktop timer that integrates with your Google Calendars. Enter your credential and choose the calendar to track your times on - I decided to set up a brand new one specifically for tracking.
Enter a tag line for your task, click start, and then click stop when you're done. Information is automatically sent to your calendar, where the agenda view provides a nice recap of your activities. It's a simple, low-resource way to keep tabs on your time.
