Display a specific range of time

how to display a specific range of time (e.g. 1800-1920)?

There currently isn’t a way to automatically zoom and scroll to display a specific range of time, but we can add it to our feature request list.

You can limit the time period that a timeline can scroll between by clicking the Date Range dropdown on the left of the zoom slider at the bottom of Timeline View. However this does not automatically zoom so that this whole date range is displayed, just adjusts the range you can scroll between.
