Autoscroll

  In addition to showing the current time, the clock allows the
  current Day view to autoscroll.  Autoscrolling causes timeslots
  that are visible in the Day view to adjust so that the current
  time is always within the first displayed timeslot.

  If the displayed day is not the current day (today), clicking on
  the clock in the Day view also causes the current day to be
  displayed instead.

  Autoscrolling can be turned off (for example, by moving the
  displayed day with the scroll bar).  If autoscrolling is turned
  off, click on the clock to restart it.
