i have two dates/time in this format mm/dd/yyyy hh:mm:ss
17/10/2001 12:35:20
21/12/2009 09:40:00

on another cell I would like the difference between these two dates in
this
format.

8 years, 11 months, 24 days, 00 hours, 20 min, 23 seconds.

or each in a different cell like these:
8 years
11 months
24 days
00 hours
