Time sheet for modx?

I need a time sheet for modx where employees can select which project they have been working on and how many hours they have spent on it. This should be so that they can go back in time to update what they have doing the past week, so it needs some basic calendar functionality. The employer should be able to add and delete employees, add and delete projects, print out working hour reports either by project name, by employee or for a certain time interval.

Anyone here know if such a module already exists for modx? Or something similar to use as an example in case I have to code it myself.

I’m not aware of any (but I could use one myself).

All I could find was some stuff just "too old" for using as a base, but I have interest on this script too.
