I took one canonical IANA zone ID from each of the different colored
regions in this article, except those that do not observe DST and do
not have a Google office. See the "Time in Europe" Wikipedia article.
As to which canonical ID to use, this was somewhat arbitrary. Brussels
was obvious, as the de facto capital of the EU. For the rest, I mostly
just went with lexicographic ordering of the most recognizable options.
I've sorted the American zones. This Keeps the U.S. ones together but
does everything alphabetically otherwise. I've added the remaining
Canadian zones These have DST (and Newfoundland is off by a half-
hour from a UTC interval) so they cannot use Etc/. The Pacific/ zones
are sort of sorted. The Chathan Islands have been added. This is the
last of the zones I believe with a non-integer hour offset from UTC.
Cosmopolitan now supports 104 time zones. They're embedded inside any
binary that links the localtime() function. Doing so adds about 100kb
to the binary size. This change also gets time zones working properly
on Windows for the first time. It's not needed to have /etc/localtime
exist on Windows, since we can get this information from WIN32. We're
also now updated to the latest version of Paul Eggert's TZ library.
