Hi,
It is possible to change time zone of specific device with following step.
1. In device list view, check target device
2. Click [More Action] > [Custom Command]
3. Enter XML like below, then click [SEND]
---------------------
<dict>
<key>RequestType</key>
<string>Settings</string>
<key>Settings</key>
<array>
<dict>
<key>Item</key>
<string>TimeZone</string>
<key>TimeZone</key>
<string>America/New_York</string>
</dict>
</array>
</dict>
---------------------

The target device must be set to supervised mode.

Hi,

thanks, that works great!
But is there also a way to create a custom settings profile with this setting for automatic deployment?

Unfortunatelly, I couldn't find a way to set time zone with Profile or other way...
Perhaps an API could be used to automate the execution of the that custom commands.
However, in that case, you would need to use WS1 Intelligence or similar.
