Startup Idea: Accounting Time Tracking Application

Startup idea to develop a background application to monitor and record the time spent on different documents or tasks. This application would automatically identify the current working document and track the amount of time spent on it, simplifying end-of-day time recording for accountants.

I work in accounting and one issue i have is tracking time. it is hard to keep track of what i am working on and how long i am working on it. it would be nice to have something run inthe background tht could identify the document I am working in and how long I am working in it so that it is easier to record my time at the end of the day.
