I am looking for time recording software.  It should do the following:-
1. This software should be running in the background and be able to
detect what applications, files, documents or emails etc. that I am
using.
2. When I open a new application, file, document or email, the
software should prompt me to enter the client ID or continue with
current client.
3. the software should automatically record the information into a
database, this information would include date and time, the client ID,
the amount of time spent and the application, file, document or email
involved.

Please supply links to at least 3 software programs that will achieve these results.
