The time stream was the pathway for the movement of time.

The Two Streams Facility of Apalapucia used time streams (which was the source of the name). Apalapucians with the Chen-7 plague were kept in the facility in different time streams, allowing them to live out their whole lives in 1 day. This also meant that each patient was kept isolated in a different time stream, but in the same place. (DW: The Girl Who Waited)
