Record deletion time stamp

Record deletion time stamp

Good afternoon,

I am familiar with both the "Added Time" and "Last Modified Time" time stamps.  On my form, the "Added Time" works wonderfully.  The "Last Modified Time" is not working as wonderfully.

Problem:  On delete, the "Last Modified Time" is displaying what appears to be random dates and times. 

Example:  These are all reports of records deleted from my form at approximately the same time on Saturday, 3 November.  Please observe the time stamp placed by the "Last Modified Time":

was removed from the  at 10/27/12 10:12:57.
was removed from the  at 10/18/12 12:14:50.
was removed from the  at 09/08/12 10:35:01.
was removed from the  at 10/14/12 14:21:38.
was removed from the  at 10/06/12 14:08:34.
was removed from the  at 09/22/12 10:28:19.
was removed from the  at 07/12/12 15:45:33.
was removed from the  at 10/06/12 14:20:29.
was removed from the  at 10/14/12 14:21:55.
was removed from the  at 10/11/12 22:04:08.
was removed from the  at 10/26/12 19:03:53.

The dates reflected here are not even close to the real "Last Modified Time", which I believe should be the exact moment the record is deleted. 

Can someone please shine some light on this subject for me?  Am I misunderstanding what "Last Modified Time" is defined by?  Thank you.
