I am trying to get more information on the Dukane synchronized clock system. I have attached the installation manual for the clock. I don't have any information on how the clock syncs. I THINK it resets at midnight by removing the power. Also in the case of a power outage there is a voltage applied to advance the secondary clocks to the correct time. I'm hoping someone worked on these at one time and knows about this system. I have searched the web pretty throughly and I can't find any decent documentation on how the system works.
