time conditions not working right

Greetings,
I'm running a camp where the person on duty needs to change every week on saturday. So I have a cascading time condition that changes the destination every week for the person on duty. I've set it up as logically as i can but the error in the log is:

WARNING[5639] pbx.c: Time range is not valid. Assuming no restrictions based on time.
