Provides the time conductor, a control which appears at the bottom of the screen allowing telemetry start and end times to be modified.

Note that the term "time controller" is generally preferred outside of the code base (e.g. in UI documents, issues, etc.); the term "time conductor" is being used in code to avoid confusion with "controllers" in the Model-View-Controller sense.
