I am in search of open-source software to track billable time for myself. A quick Google search did not find anything that is open-source but I am hoping that this group might know of such software? The platform is C7.

I am looking for suggestions for open-source time tracking software to run on CentOS. If the data can be stored in my own central database, that is a plus, as is the potential availability of some client that can run on Android.

Thank you.
