do the wireless clocks update?
110V and 24V clocks update every minute. The battery-operated clocks receive for 30 minutes following initial power up and then for 5 seconds each 4 hours (12, 4 and 8 o’clock). Upon successful reception, they retransmit the correction signal to adjacent clocks. If signal is not received, the battery operated clocks increment their receive time with each attempt until successful reception occurs.
