Before the patch %z would always expand to +0000 on Linux and to the
name of the local time zone on Windows, no matter which offset was
actually given.  So it was broken in either case (even though it got
at least some aspects right by accident for some commits).  Based on
that I'd think handling %z internally should be OK.

But there's more.  strftime on Windows doesn't support common POSIX-
defined tokens like %F (%Y-%m-%d) and %T (%H:%M:%S). We could handle
them as well.  Do we want that?  At least we'd have to update the
added test that uses them..

Here's the full list of tokens in POSIX [1], but not supported by
Windows [2]: %C, %D, %F, %G, %R, %T, %V, %e, %g, %h, %n, %r, %t, %u
plus the modifiers %E and %O.
