My files do not show Woods 13360.
I am very interesting to identify your timer.
If you have outdoor timer, then timer photoeye can be getting feedback from surrounding lights.
If you have indoor hardwire timer, then white and red wires are probably connected incorrectly.
1) Open following link to identify timer and download manual, and then add a comment and say which timer resembles your timer. From there I can add a comment with possible solution.
