Sometimes there is a need to provide unqiue timezone for Wi-Fi APs managed from cnMaestro but deployed across different time zones. We can make use of "User Defined Overrides" in AP Group to achieve this one. Go to AP group and configure below option in "User Definied Override section".
timezone ${Time Zone=America/Belem}
With this default Time zone set to America/Belem. From the Wi-Fi device configuration tab, we can now configure unique time zone for each device. cnMaestro UI screen shots attached for the reference
