-# In comp.risks 14.87 (26 August 1993), Peter Neumann writes:
+# From an AP article (1993-08-22):
-# I wonder what happened in Kwajalein, where there was NO Friday,

+# From Phake Nick (2018-10-27):
+# <https://wiki.suikawiki.org/n/南洋群島の標準時> ... pointed out that
+# currently tzdata say Pacific/Kwajalein switched from GMT+11 to GMT-12 in
+# 1969 October without explanation, however an 1993 article from NYT say it
+# synchorized its day with US mainland about 40 years ago and thus the switch
+# should occur at around 1950s instead.
+#
+# From Paul Eggert (2018-11-18):
+# The NYT (actually, AP) article is vague and possibly wrong about this.
+# The article says the earlier switch was "40 years ago when the United States
+# Army established a missile test range here".  However, the Kwajalein Test
+# Center was established on 1960-10-01 and was run by the US Navy.  It was
+# transferred to the US Army on 1964-07-01.  See "Seize the High Ground"
+# <https://history.army.mil/html/books/070/70-88-1/cmhPub_70-88-1.pdf>.
+# Given that Shanks was right on the money about the 1993 change, I'm inclined

 # N Mariana Is, Guam
+# From Phake Nick (2018-10-27):
+# Guam Island was briefly annexed by Japan during ... year 1941-1944 ...
+# however there are no detailed information about what time it use during that
+# period.  It would probably be reasonable to assume Guam use GMT+9 during
+# that period of time like the surrounding area.
+# From Paul Eggert (2018-11-18):
 # Howse writes (p 153) "The Spaniards, on the other hand, reached the
 # Philippines and the Ladrones from America," and implies that the Ladrones
 # (now called the Marianas) kept American date for quite some time.
 # For now, we assume the Ladrones switched at the same time as the Philippines;
 # see Asia/Manila.
+#
+# Use 1941-12-10 and 1944-07-31 for Guam WWII transitions, as the rough start
+# and end of Japanese control of Agana.  We don't know whether the Northern
+# Marianas followed Guam's DST rules from 1959 through 1977; for now, assume
+# they did as that avoids the need for a separate zone due to our 1970 cutoff.
+#
 # US Public Law 106-564 (2000-12-23) made UT +10 the official standard time,
 # under the name "Chamorro Standard Time".  There is no official abbreviation,

 # Alan Eugene Davis writes (1996-03-16),
 # "I am certain, having lived there for the past decade, that 'Truk'
 # (now properly known as Chuuk) ... is in the time zone GMT+10."
 #
 # The Federated States of Micronesia Visitors Board writes in
 # The Federated States of Micronesia - Visitor Information (1999-01-26)
 # http://www.fsmgov.org/info/clocks.html
 # that Truk and Yap are UT +10, and Ponape and Kosrae are +11.
 # We don't know when Kosrae switched from +12; assume January 1 for now.
+# From Phake Nick (2018-10-27):
+#
+# From a Japanese wiki site https://wiki.suikawiki.org/n/南洋群島の標準時
+# ...
+# For "Southern Islands" (modern region of Mariana + Palau + Federation of
+# Micronesia + Marshall Islands):
+#
+# A 1906 Japanese magazine shown the Caroline Islands and Mariana Islands
+# who was occupied by Germany at the time as GMT+10, together with the like
+# of German New Guinea.  However there is a marking saying it have not been
+# implemented (yet).  No further information after that were found.
+#
+# Japan invaded those islands in 1914, and records shows that they were
+# instructed to use JST at the time.
+#
+# 1915 January telecommunication record on the Jaluit Atoll shows they use
+# the meridian of 170E as standard time (GMT+11:20), which is similar to the
+# longitude of the atoll.
+# 1915 February record say the 170E standard time is to be used until
+# February 9 noon, and after February 9 noon they are to use JST.
+# However these are time used within the Japanese Military at the time and
+# probably does not reflect the time used by local resident at the time (that
+# is if they keep their own time back then)
+#
+# In January 1919 the occupying force issued a command that split the area
+# into three different timezone with meridian of 135E, 150E, 165E (JST+0, +1,
+# +2), and the command was to become effective from February 1 of the same
+# year.  Despite the target of the command is still only for the occupying
+# force itself, further publication have described the time as the standard
+# time for the occupied area and thus it can probably be seen as such.
+#  * Area that use meridian of 135E: Palau and Yap civil administration area
+#    (Southern Islands Western Standard Time)
+#  * Area that use meridian of 150E: Truk (Chuuk) and Saipan civil
+#    administration area (Southern Islands Central Standard Time)
+#  * Area that use meridian of 165E: Ponape (Pohnpei) and Jaluit civil
+#    administration area (Southern Islands Eastern Standard Time).
+#  * In the next few years Japanese occupation of those islands have been
+#    formalized via League of Nation Mandate (South Pacific Mandate) and formal
+#    governance structure have been established, these district [become
+#    subprefectures] and timezone classification have been inherited as standard
+#    time of the area.
+#  * Saipan subprefecture include Mariana islands (exclude Guam which was
+#    occupied by America at the time), Palau and Yap subprefecture rule the
+#    Western Caroline Islands with 137E longitude as border, Truk and Ponape
+#    subprefecture rule the Eastern Caroline Islands with 154E as border, Ponape
+#    subprefecture also rule part of Marshall Islands to the west of 164E
+#    starting from (1918?) and Jaluit subprefecture rule the rest of the
+#    Marshall Islands.
+#
+# And then in year 1937, an announcement was made to change the time in the
+# area into 2 timezones:
+#  * Area that use meridian of 135E: area administered by Palau, Yap and
+#    Saipan subprefecture (Southern Islands Western Standard Time)
+#  * Area that use meridian of 150E: area administered by Truk (Chuuk),
+#    Ponape (Pohnpei) and Jaluit subprefecture (Southern Islands Eastern
+#    Standard Time)
+#
+# Another announcement issued in 1941 say that on April 1 that year,
+# standard time of the Southern Islands would be changed to use the meridian
+# of 135E (GMT+9), and thus abolishing timezone different within the area.
+#
+# Then Pacific theater of WWII started and Japan slowly lose control on the
+# island.  The webpage I linked above contain no information during this
+# period of time....
+#
+# After the end of WWII, in 1946 February, a document written by the
+# (former?) Japanese military personnel describe there are 3 hours time
+# different between Caroline islands time/Wake island time and the Chungking
+# time, which would mean the time being used there at the time was GMT+10.
+#
+# After that, the area become Trust Territories of the Pacific Islands
+# under American administration from year 1947.  The site listed some
+# American/International books/maps/publications about time used in those
+# area during this period of time but they doesn't seems to be reliable
+# information so it would be the best if someone know where can more reliable
+# information can be found.
+#
+#
+# From Paul Eggert (2018-11-18):
+#
+# For the above, use vague dates like "1914" and "1945" for transitions that
+# plausibly exist but for which the details are not known.  The information
+# for Wake is too sketchy to act on.
+#
+# The 1906 GMT+10 info about German-controlled islands might not have been
+# done, so omit it from the data for now.
+#
+# The Jaluit info governs Kwajalein.
 # Midway
 # From Charles T O'Connor, KMTH DJ (1956),
 # From Paul Eggert (2003-03-23):
 # We don't know the date of that quote, but we'll guess they
 # started DST on June 3.  Possibly DST was observed other years
 # in Midway, but we have no record of it.
+# Nauru
+# From Phake Nick (2018-10-31):
+# Currently, the tz database say Nauru use LMT until 1921, and then
+# switched to GMT+11:30 for the next two decades.
+# However, a number of timezone map published in America/Japan back then
+# showed its timezone as GMT+11 per https://wiki.suikawiki.org/n/ナウルの標準時
+# And it would also be nice if the 1921 transition date could be sourced.

+# From Paul Eggert (2018-11-19):
+# The 1921-01-15 introduction of standard time is in Shanks; it is also in
