Probably the best method would be to build a WWVB or GPS 60Hz synchronized clock and designate that one a master and feed the others with that signal. Another possibility would be to build a small 60 Hz alternator with a WWVB or GPS synchronized phase locked loop to control it's frequency and just power all the line frequency clocks from that source independent of the utilities grid...regards...
