There's a complete collection of these in a file on the "Lisp Utilities
Repository".  I believe it's called date-formatter.lisp.  Here is the
readme file from the repository.  (note: this question is not mcl specific,
so it should have been asked on the common-lisp@ai.sri.com list.  Send mail
to common-lisp-request@ai.sri.com to get added.)

Hope this helps
