Except that I just tested, and nl_langinfo(_DATE_FMT) for both Cygwin
and Linux is

%a %b %e %H:%M:%S %Z %Y

so something else weird is going on.

Oh duh, it's locales!  nl_langinfo() is locale-specific, and you are
(probably) running in a default locale of en_US rather than the C locale.

$ date
Wed, Aug 31, 2016  9:39:55 AM
$ LC_ALL=C
Wed Aug 31 09:43:42 CDT 2016

So, the answer to your question is determined by what your locale thinks
is the appropriate representation; and I have no control over whether
Windows' locale defaults will match glibc's locale defaults for en_US or
any other locale outside of C.
