This is for the part of Papua New Guinea that plans to switch from
UTC+10 to UTC+11 on 2014-12-28 at 02:00. (Thanks to Kiley Walbom
for the heads-up.)
* australasia (Pacific/Bougainville): New zone.
* zone.tab, zone1970.tab: Add entries for it.
* NEWS: Document this.
It allows multiple country codes per zone. Switch code and data to
use the new format, along with the recently-added Crozet Islands entry.
The old zone.tab file is still installed but is deprecated.
The new file uses UTF-8; add commentary saying that iso3166.tab is
planned to change to UTF-8.

* NEWS: Document the above.
* northamerica (America/Metlakatla): Use the more-common "PST"
rather than our invented "MeST" for the abbreviation. Our source
called it "Pacific Time", as did a contemporaneous news report,
and I couldn't find contemporaneous use of "MeST" or of
"Metlakatla Time". Cite the news report in the commentary,
and quote some Juneau graffiti.
* zone.tab (America/Resolute): Call it Central Time, not Central
Standard Time, since it observes DST now.
(America/Metlakatla): Call it Pacific Standard Time, not
Metlakatla Time. Mention that it's in Alaska.

My best guess is that the Asia/Tiksi entry is a false alarm,
and that the area hasn't diverged from Yakutsk since 1970.
* europe: Move zone.tab comments to zone.tab.
(Asia/Yakutsk): Move comment for Bulunsky district here,
Remove a comment about a draft Asia/Tiksi zone, containing the
Bulunsky district. We don't have sufficient evidence that it
ever diverged from Yakutsk after 1970.

This was experimental, and it appears that the tzwinnow
approach will be better. We need to cut a new stable
release soon, and the -t option might make it harder to
integrate tzwinnow later, so let's omit -t for now.
* .gitignore: Remove time.tab.
* Makefile (ZONETABTYPE): Remove. All uses removed.
(time.tab): Remove. All uses removed.
* Theory: Omit discussion of time.tab.

* tzselect.8: Omit -t and time.tab.
* tzselect.ksh (ZONETABTYPE): Remove. All uses removed.
Remove -t ZONETABTYPE option.
* zone.tab: Restore first comment line, since there's no longer
a need to distinguish this file from time.tab.
* northamerica (America/Cayman, America/Jamaica, America/Grand_Turk):
Change KMT from -5:07:12 to -5:07:11 (should be -5:07:10.41).
* zone.tab: Fine-tune geographical coordinates to match -5:07:10.41.
I chose the latitude to match the General Post Office, Kingston,
in the city center according to Google Maps.
This is like the previous change, except it entails a change to zone.tab.
The America/Montreal entry was created only because we mistakenly
thought that Montreal's and Toronto's post-1970 time stamps differed.
* backward, northamerica (America/Montreal):
Now a 'backward' link to America/Toronto.
* northamerica (Mont): Remove rules; no longer needed.
(America/Thunder_Bay): Refer to Toronto rules, not Mont.
This doesn't change any time stamps.
* zone.tab (America/Montreal): Remove.
(America/Toronto): Say that it also covers most of Quebec.
This is a backwards-compatible way of transitioning to a less
politically-charged approach to choosing TZ values. A new time
zone table time.tab acts like zone.tab, except it omits TZ values
that are present only for political reasons. tzselect has a new
"-t zonetabtype" option that lets users select which time zone table
to use, and installers can select the default table. The zone.tab
file does not change, and the default tzselect table for now is
zone.tab. This avoids the backward-compatibility concerns
expressed on the tz mailing list; see, for example,
the discussion surrounding Derick Rethans's comments in
<http://mm.icann.org/pipermail/tz/2013-August/019544.html>
* .gitignore: Add time.tab.
* Makefile (ZONETABTYPE): New macro.
(TABDATA): Add time.tab.
(all): Depend on $(TABDATA).
(install): Do not depend on $(TABDATA), since $(DATA) includes it.
Install time.tab too.
(time.tab): New rule.
(tzselect.tab): Substitute ZONETABTYPE.
* zone-time.awk: New file.
* tzselect.8: Document new options, and --help and --version while
we're at it.
* tzselect.ksh (ZONETABTYPE): New var.
Implement -t ZONETABTYPE option.
Check that no extra operands are given.
* zone.tab: Change first comment line, to distinguish the two
tables better.
This unnecessary duplicate of America/Denver was confusing, as it
incorrectly implied that 'Mountain Time - Navajo' differed from
'Mountain Time' either now or in the past. Clarify this in a
better way, by mentioning in the Arizona entry that it doesn't
include Navajo.
* iso3166.tab, zone.tab: Make it clear that country codes aren't
necessarily for countries. Thanks to Derick Rethans for spotting this.
* zone.tab (Antarctica/McMurdo, Europe/Mariehamn, Europe/Sarajevo)
(America/St_Barthelemy, America/Kralendijk, Europe/Busingen)

(Europe/Podgorica, America/Marigot, Europe/Skopje, Europe/Ljubljana)
(Arctic/Longyearbyen, Europe/Bratislava, Europe/San_Marino)
(America/Lower_Princes, Europe/Vatican):
Undo recent changes, going back to the way these entries were done
in the last tz distribution. Only the Antarctica/South_Pole change
was retained.
This continues in the series of moving entries to 'backward' if
they exist only because of obsolete tz rules about country codes.
This change does not affect any time stamps after 1970. Unlike
the previous change in this series, this one does affect time
stamps before 1970, but that's OK as pre-1970 time stamps are
out of scope for the tz database.
* antarctica (Antarctica/McMurdo, Antarctica/South_Pole):
Move to 'backward' and link to Pacific/Auckland.
* backward: Move links here from 'antarctica'.
* zone.tab: Coalesce McMurdo and South Pole, and add Scott Base
to the description.
* backward: Move links here from other files, if the only reason
they existed was to fill out zone.tab. Zones are now allowed to
cross national borders, so a zone now need not exist merely
because there's a national border. Sort the list consistently.
None of this changes any time stamp in the database.
* checktab.awk: Don't require that zone.tab's column 3 be unique.
* europe (Europe/Jersey, Europe/Guernsey, Europe/Isle_of_Man)
(Europe/Mariehamn, Europe/Busingen, Europe/Vatican, Europe/San_Marino)
(Arctic/Longyearbyen, Europe/Ljubljana, Europe/Podgorica)
(Europe/Sarajevo, Europe/Skopje, Europe/Zagreb, Europe/Bratislava):
* northamerica (America/St_Barthelemy, America/Marigot):
* southamerica (America/Lower_Princes, America/Kralendijk):
Move links to 'backward'.
* zone.tab: Give more details about how different rows can have
duplicate column 1 or column 3. For each link moved to 'backward',
change column 3 to be the non-backward name.
This change stemmed from a long discussion on the tz mailing list
about what country the Jerusalem zone entry is in. The idea of
this change is to deemphasize the role of countries in the tz
database, to lessen the amount of controversy in the future.
Due to backward compatibility concerns this change does not eliminate
the role of countries entirely. With one minor exception this
change does not alter any code or data, just comments.
* Theory, zone.tab: Deemphasize the role of countries in choosing
location names, as they tend to introduce political conflict
during maintenance, and country information isn't needed for
typical uses of the database.
* Theory: Say that names should differ in more than just case, and why;
and explain why 'backward' means old names will continue to work.
(thanks to Norbert Lindenberg for spotting these issues).
Update citation date and URL.
* iso3166.tab: Mention latest maintenance update.
Update citation URL. Add missing comma for BQ.
Be more consistent about abbreviating Sint like Saint.
Mention SX "Dutch part" for consistency with MF "French part".
* iso3166.tab, zone.tab: Add legal/territorial disclaimer.
* zone.tab: Say that country/zone overlaps can occur in both
directions, and that column 2 need not lie within column 1.
(Asia/Jerusalem): Change the coordinates from a sloppy value,
taken from an old astrology book, to a more-precise value, the
site of city hall. The sloppy value sparked some controversy and
the hope is that the more-precise value will be a bit less
controversial.
Also, sort Macquarie more-consistently with other parts of Australia.
This doesn't affect time stamps, just zone selection.
Problems reported by Tim Parenti in
<http://mm.icann.org/pipermail/tz/2013-April/019060.html>.
* australasia (Antarctica/Macquarie): Tasmania Parks & Wildlife Service
history indicates that permanent habitation was 1899-1918 and 1948 on.
* zone.tab (Antarctica/Macquarie): Move next to Lord Howe and Tasmania.
This doesn't affect time stamps, just zone selection.
Problem reported by Tobias Conradi in
<http://mm.icann.org/pipermail/tz/2013-April/019023.html>.
* antarctica (AusAQ, ATAQ): Remove; no longer needed.
* australasia (Antarctica/Macquarie): Move here from
the 'antarctica' file. Use Aus and AT rather than
AusAQ and ATAQ.
* zone.tab (Antarctica/Macquarie): Country code AU, not AQ.
