zoneinfo for Gentoo has these (non-conteninents):

Brazil
Canada
Chile
GB
GB-Eire
Greenwich
Hongkong
Iceland
Indian
Iran
Israel
Jamaica
Japan
Kwajalein
Libya
Mexico
Mideast (maybe a continent in zoneinfo terms)
Navajo
PRC
Poland
Portugal
Singapore
Turkey
Zulu

However, zone.tab only lists things of the form continent/city, so
maybe those are all non-standard, or at least not usable by programs
that read the zone.tab file?

Well, it is a valid zoneinfo file, but maybe not being listed in
zone.tab is what's breaking things.  I've found that KDE tends to try
to be clever and to not throw up error messages when it finds that a
system is broken.  It would be really nice to have error messages
rather than auto-reparation, even if as a compile-time option.
