Thanks for all those heads-ups about New Zealand. In nosing around
the web I think Haiti has probably changed to not use DST, so let's go
with that change too (it's the most pressing, as it affects today's
time stamps). Here are all the changes that I have accumulated, not
counting the proposed zic.c change already discussed.
Changes affecting current time stamps:
* Haiti no longer observes DST. (Thanks to Stephen Colebourne for this.)
Changes affecting past and future time stamps:
* The Turks and Caicos switch at 02:00, not at 00:00, and have adopted
US DST rules. (Thanks to Chris Dunn and Brian Inglis for this.)
Changes affecting future time stamps only:
* New Zealand is extending DST, starting later this year.
(Thanks to Colin Sharples and many others for this info.)
Changes affecting commentary only:
* The Caprivi Strip unofficially does not observe DST, but we currently
have no further details. (Thanks to Petronella Sibeene for this.)
