Cygwin provides all locales supported by the underlying Windows system.
Windows doesn't know en_DK.

Linux (better: glibc) supports en_DK, but what you say doesn't work for
me on Linux either:

  $ LC_TIME=en_DK date
  Thu Sep  1 20:30:01 CEST 2011

No ISO 8601 representation.

There is no such locale.  I tried your above grep on the Linux locales
(on F15, glibc 2.14), too, and there isn't even one which has ISO 8601
date/time by default.

If you want that date format, you have to enforce it on a per-command
base, for instance:

  $ date +'%F %T'
  $ ls -l --time-style=long-iso
  $ ls -l --time-style='+%F %T'
