There’s the right side pop-out menu. Use that to access time tracking to clock in to jobs and track time to them. Yes, that’s the only way to track jobs, without giving access to editing time punch data.
Also, look for the '?' icon on the right side of the page to find a tutorial for it. If you're on your home page, you'll see the tutorial for using the Time Tracking feature!
