The main Transmitter transmits (broadcast) time to 72MHz Analog Clocks, Digital Clocks, Digital Timers, and Repeater Transmitters. The Legacy Time Zone sets the time zone received by these devices.
This setting does not apply to Notify InfoBoards. These device types receive UTC time from either a Transmitter or a NTP time source and then synchronize received UTC time to their assigned Time Zone and apply DST rules.
Go to Devices > Transmitters.
From the list, select the Name link of the Transmitter. Its profile is displayed.
Select Show Advanced Options.
From the Legacy Clock Time Zone drop-down menu, select a Time Zone.
When a setting update is made to a device, its Update Pending status is set to Yes. During its next check-in, all pending setting updates are downloaded to the device. Once downloaded, its Update Pending status is set to No.
Once the update is downloaded to the main Transmitter, devices receive the update at their next search frequency.
