These clocks are operated from a central controller. A simplex clock is of no use without the controller which in our case receives a signal based on the atomic clock. Just a fun fact: utility companies have to average exactly 60 hertz over a 24 hour period in order to keep your plug in clocks accurate.<br><b>References : </b><br> I work in a hospital and we have the same clocks.

Schools and businesses used these in the 50's and Early 60's and they required one or more "Master" clocks which synchronized the slave units. The Master was usually the one in the "Office" which was set manually and the others synchronized to it by advancing the time about one minute per second until it displayed the correct time. I don't know if there was a way to manually override the time on the slave units. Your description makes me very suspicious that it is not possible.
