Say our data in cols A & B is:

Aegir 9/2/2008
Albiorix 2/21/2008
Anthe 2/3/2008
Atlas 1/6/2008
Bebhionn 5/22/2008
Bergelmir 9/28/2008
Bestla 3/31/2008
Calypso 11/15/2008
Daphnis 3/5/2008
Dione 12/3/2008
Enceladus 5/22/2008
Epimetheus 12/21/2008
Erriapus 8/31/2008
Farbauti 7/25/2008
Fenrir 12/31/2008
Fornjot 1/1/2008
Greip 4/16/2008
Hati 2/13/2008
Helene 9/16/2008

First we sort cols A & B by B and then in C1 enter:
=A1&TEXT(B1,"mm/dd/yyyy") and copy down to see:

Fornjot01/01/2008
