I tried these on a number of unix  systems  (RH  8  and  9,
FreeBSD,  OSX, and a couple others), and I never got a data
of the form "yyyy-mm-dd".  All were of  the  form  "DD  Mmm
yyyy". The two different LANG values never changed anything
from ls's default.

So where does "LANG=en_US.UTF-8" actually have an effect?
