If you like this, you should check out http://wakatime.us which is a free time tracker for Sublime that works with Git to display how much time you work in each project and even in each branch.
Looks interesting, but I'm turned off by 'sign up for free' when there's nothing on the page indicating the cost, if any, of using the product.
If it's free, 'sign up for free' suggests otherwise. If there's a cost, please be up front about it. If you haven't decided what or whether to charge, just say so ;)
