A main Transmitter receives UTC time from either a GPS or NTP time source and then sets its internal clock to its configured time zone. The Transmitter wirelessly transmits its internal clock time that is received by 72MHz Analog Clocks, Digital Clocks and Timers and Repeater Transmitters. A Transmitter's time zone is configured from its Legacy Time Zone setting.
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.
