Closest I could find is this chart:

http://unicode.org/cldr/data/diff/supplemental/windows_tzid.html

We could at least provide this, and if the mapping fails we could print
a message that it's an unknown string, and the user can submit a bug.
%Z could show the full Windows-provided name, which IMHO is better than
nothing.

In addition, we can attempt to guess the right value based on the
localized string and offset, e.g. Hebrew is probably Israel's time
zone.  But this is a lot of work.
