Yes. D_T_FMT yields a similar output to _DATE_FMT, but it lacks the
timezone identifier. So I had thought to use the format specifiers directly
and bypass the call to nl_langinfo. I was told that _DATE_FMT was added
because Sun made everything up to date with the latest xopen std. I don't
yet grok the localization stuff. So, I'm wondering if passing the format
specifiers into strftime directly would remove any localizing done by
nl_langinfo?
