Forwarding Outlook Appointments Sent Date

Yesterday we noticed, and confirmed on several more computers running Windows XP and Outlook 2003, that when you select a calendar item and choose Forward – the body of the new form is prefilled with a strange original date & time SENT stamp (7/1/05 10:44). All have the same date/time – anyone else see this or know where it’s coming from?
