Last 14 years as freelancer I was using a horrible number of time capturing systems. Actually I am using about three at a time now. There are so many of them, and most companies invent their own - starting with excel.
Time for a break
There's nothing special about such a system. At least it should be able to make me capture my time once, store it and provide some interfaces to other (legacy) systems. There must be import and export interfaces, it should support several of the current technologies like http, xml-rpc ... and it should have a web interface when it starts.

So, here we go. Let's design and implement such a system for free (the only chance to make it used everywhere and then - save time for everyone).
