A great and nice looking app that I think might let you do this, is called Concentrate Timer. It's free and i've used it for time management/tracking before.I'm looking for a really simple app that can be used for time tracking. Now, I want very simply time tracking...nothing that does this complicated billing or anything. basically, at work, it'd be nice to know how much time I spend on fixing an issue. Ideally, I'd be able to hit a button to start tracking and then a button to stop tracking time and it'd be continuous until then. Even better is the ability to handle multiple issues at the same time. I may just need to write some kind of javascript web app to do this myself...
