Yeah... I basically need something that will do this:
1.) User logs in and clicks button to "clock in"
2.) User later works on tickets / assignments (tracked in database)
3.) User later clicks button to "clock out" and then logs out
4.) Admin can define who gets what pay-rate
Now, during all of these times, pay-rates are "hard-coded" so that they can't be changed later. Of course, if there's a plugin for Trac or something, that would work as well....
