There are several definitions of time in the Control Panel. For instance, there is the user's setting of time zone. Then, there is also each device has a time zone set with it. Finally, I believe Carriots logs everything in UTC-0 time zone.
Therefore, when I am looking at stream data, the interface isn't obvious which time zone I am looking at. I suspect UTC-0. If so, it would be helpful to have some sort of indication of this. Also, since I am not in UTC-0, maybe a clock could be shown inside the Control Panel. Eventually, it would be nice to have a user setting so that the user can determine how all times are displayed in the Control Panel.
