Not working with Maverick update

I love iCheckClock. I use it every day. Unfortunately, it does not work with the new Maverick update. It acts like it it working fine, but after testing it several times…noting when I started the clock…it is obvious it is not keeping time correctly. Right now I have 13.58 minutes on a clock that I started 58 minutes ago. Please fix ASAP!
