Rachota Project – Time Tracking Tool for Precise Measurement of Human Work at Computer
http://rachota.sourceforge.net/

Rachota is a small application for those who work with computers on a daily basis and are curious how efficiently they use their time. It is basically a scheduler that measures how much time one spends on pre-defined tasks during a day. The data can be used later for backward evaluation or generation of reports e.g. for managers. This has been added to the tools section of Research Resources Subject Tracer™ Information Blog.
