If the following is entered in an org-mode file:

* Follow up telephone enquiry (call made [2008-10-18 Sat 15:35])
  SCHEDULED: <2008-10-25 Sat>

The agenda then displays:

Saturday  25 October 2008
  home:       15:35...... Scheduled:  Follow up telephone enquiry (call made [2008-10-18 Sat 15:35]

Why does the agenda schedule the item using the time from the inactive timestamp?

Thanks
