This will allow any other camera connected to the Solo to be triggered by the Solo's shutter controls if no GoPro is connected. So, if no GoPro is connected, it will send the mavlink command for triggering the shutter in ArduCopter. Whatever servo output have defined as a camera trigger will fire.
User or app needs to change /usr/bin/extSettings.conf "timeOffsetHrs" to be their local time offset from UTC in hours. The default is "None", and the clock will not update. The Solo has no other way to know what timezone it is in, so this must be set manually or with the app. If set, for example to -5, the GoPro clock will automatically be set for the current UTC time minus 5 hours (eastern standard time).
