Free project time software for windows

Project Timers will enable you to easily manage the time spent on documents for various tasks/projects while working on the computer.
Project Timers works on a very simple principle: You create a timer and provide it with a keyword to sniff/detect.
As such, each time you work on a document whose titlebar contains that keyword the corresponding timer will start counting.
If your work is organized so that each project you work on has a docket number (or a database serial) appearing in the filename of each related document, then if you create a timer to sniff that serial you essentially keep track of time spent on that project.
Project Timers is a useful application for monitoring the time spend on various tasks.
