The animation and timeline widgets display time in UTC. I don't see any options to change this. Is it possible to have the widgets display local time?
The Animation widget as official support for this via the AnimationViewModel.defaultDateFormatter and AnimationViewModel.defaultTimeFormatter properties. The Timeline is still rough around the edges, but you you can assign the Timeline.makeLabel function directly to override the label making.
In all three cases, they take a JulianDate time and return a strong. It should be easy to have them return local time strings. Eventually we’ll make all of this a little easier.
