find or ls -l recursive output in YYYY-MM-DD format on FreeBSD

I'm trying to list files recursively with this date format YYYY-MM-DD on a on FreeBSD. I tried the Linux commands I know but none of them worked :

$ ls -lR --time-style=+'%Y-%m-%d %T'
ls: unrecognized option '--time-style=+%Y-%m-%d %T'
usage: ls [-ABCFGHIJLOPRSTUWYZabcdefghiklmnopqrstuwxyz1,] [-D format] [file ...]
$ find . -printf "%TY-%Tm-%Td %p\n"
find: -printf: unknown primary or operator
$

How can I do that ? EDIT0 : I added the recursive word in the title because it was only in the content of my question. BTW : I forgot that ls -lR is a pain to grep so I'm more interrested in a find like solution :)
