Hi,
Based on my research, I didn't find the setting to set timezone on Android device in Intune.
For the OMA-URI setting, based as i know, there aren't many public resources available as this is dependent on the the software vendor. Due to the setting with Android, the information comes from the developer of the Android platform. Microsoft Intune can only use the capabilities that can be managed.
The information on Android I always research is under :http://developer.android.com/guide/topics/admin/device-admin.html#policies.
Hope it can help.
