docs: Checks if the section contains the given time and fires an event
  in case the value "entered" or "left" the section. With this one
  can react if a time "enters"/"leaves" a specific region in a gauge.
  This can be useful to control things like switching lights on if
  the time enters the region and switching it of again when the time
  left the region.
