I found a [very good webbased time tracker](http://formassembly.com/blog/introducing-time-tracker-a-personal-time-management-solution), with the latest en-vogue technology (AJAX, type-ahead).
You can test it anonymously or register for free and get to save your timed tasks.
It is free, webbased (=> data is globally available), snappy (due to AJAX usage), and beautifully designed.
