Hello Folks,
I was searching for an open source time tracking system and I found this "KIMAI". It's GUI is easy to understand and to customize as well.
Kimai
Kimai is based on PHP5/MySQL5 technology. If you don’t have a web server installed on your machine you can use XAMPP (Windows and Mac). XAMPP comes with everything you need for Kimai.
Kimai is a free open source timetracker. It tracks work time and prints out a summary of your activities on demand. Yearly, monthly, daily, by customer, by project, by action…
It’s simplicity is its strength. Due to Kimai’s web browser based interface it runs cross-platform. Likewise you can install it as a web service or as a single-user program on your local workstation.
“While there are many programs one can use for time and project tracking, they tend to be overkill for my rather simple needs. Kimai came about because I was tired to feed lame boring excel tables …”
Kimai does not have to run to do the recording. You can even quit your browser. Your time is still recording until you stop it from any web browser that has access to your installment. It is designed to hold lots of users but you can use it for a single user if you need to.
Kimai is localized in English, German, Dutch, Spanish, French, Italian and Portuguese so far. Feel free to send your self-made language files! Not all localizations are complete – we’re still looking for translators!
You can also send us your own skin designs (find instructions in the ‘skins’ directory). We will also have some skins available in the future.
