I’ve been using Kimai [1] for a bit over a year to track my freelancing work for various clients as well as the work I do for my own projects. I can definitely recommend it!
It's easy to install and very pleasant to use for tracking time.
Entries have an "exported" flag to mark if you've already billed for a certain hour or not. You could also generate invoices directly from Kimai but I'm not using that feature because I'm creating my invoices in another program.
