OK, thanks.

I really don't care which function lets you format a time to produce a timezone
name on Windows. If `format-time-string' continued to do that, that would be
more backward-compatible, but that's not a biggee. It would be fine if it were
some other function  (or some other format key, besides %Z) that provided this
feature. Just so we don't lose all ability to do this.

For the record, I probably will use %z for my application. But I feel
nevertheless that we should continue to provide some way to produce a timezone
name (on Windows), however rudimentary, language-specific, or non-compliant that
name might be.
