Does anyone here know a thing or two about synchronized clocks? I'm thinking about how nice it would be to have "official theatre time" in all the important areas (booth, box office, dressing rooms, greenroom, orch "pit" (scene shop usually), SM Console, etc). There seem to be lots of [expensive] buy-new options, but I also see some used options that could work for us - usually Bogen or Rauland systems that have been decommissioned from schools. Seems that one can mount a rackable "master clock", a 24v PSU (has to be compatible with the system), and then daisy-chain a bunch of "school clocks" using low voltage wiring. I would prefer wired since we wouldn't need to keep up with batteries. I'd love to hear anyone's experiences with this. @RonHebbard this seems to be in your wheelhouse. I am familiar with Atomic Clocks like these, but they really seem to drain the batteries and they're a bit 'fancy'. These ITC Clocks from Uline could also be an option. While batteries would need to be replaced periodically, I guess that might ultimately be better than wiring in a bunch of antique wall clocks.
