# stated that fallback would occur on the next day (the 1st)'s "03:00 am (Hong
# Kong Time 04:00 am)" and the clock will fall back for a half hour. (03:00
# probably refer to the time commonly used in mainland China at the time given
# the paper's background) ... the sunrise/sunset time given by South China
# Morning Post for October 1st was indeed moved by half an hour compares to
# before. After that, in December, the battle to capture Hong Kong started and
# the library doesn't seems to have any record stored about press during that
# period of time. Some media resumed publication soon after that within the
# same month, but there were not much information about time there. Later they
# started including a radio program guide when they restored radio service,
# explicitly mentioning it use Tokyo standard time, and later added a note
# saying it's half an hour ahead of the old Hong Kong standard time, and it
# also seems to indicate that Hong Kong was not using GMT+8 when it was
# captured by Japan.

# I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates,

# I used the following code in GNU Emacs 26.1 to generate the "Rule Iran"

#
# 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

# 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;

# Use 1941-12-10 and 1944-07-31 for Guam WWII transitions, as the rough start

# 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

# From Paul Eggert (2018-11-30):
# A brief but entertaining history of time in Indiana describes a 1949 debate
# in the Indiana House where city legislators (who favored "fast time")
# tussled with farm legislators (who didn't) over a bill to outlaw DST:
# "Lacking enough votes, the city faction tries to filibuster until time runs
# out on the session at midnight, but rural champion Rep. Herbert Copeland,
# R-Madison, leans over the gallery railing and forces the official clock
# back to 9 p.m., breaking it in the process. The clock sticks on 9 as the
# debate rages on into the night. The filibuster finally dies out and the
# bill passes, while outside the chamber, clocks read 3:30 a.m. In the end,
# it doesn't matter which side won. The law has no enforcement powers and
# is simply ignored by fast-time communities."
# How Indiana went from 'God's time' to split zones and daylight-saving.

# From Joseph Myers (2018-11-18):
# An astronomer before 1925 referring to GMT would have been using the old
# astronomical convention where the day started at noon, not midnight.
#
# From Steve Allen (2018-11-17):
# Meteorological Observations made at the Hongkong Observatory in the year 1904
# page 4 <https://books.google.com/books?id=kgw5AQAAMAAJ&pg=RA4-PA4>
# ... the log of drop times in Table II shows that on Sunday 1904-10-30 the
# ball was dropped. So that looks like a special case drop for the sake
# of broadcasting the new local time.
#
# From Phake Nick (2018-11-18):
# According to The Hong Kong Weekly Press, 1904-10-29, p.324, the
# governor of Hong Kong at the time stated that "We are further desired to

# dropping of the Ball at 23min. 18sec. before one."

# From Phake Nick (2018-10-26):
# I went to check microfilm records stored at Hong Kong Public Library....
# on September 30 1941, according to Ta Kung Pao (Hong Kong edition), it was
# stated that fallback would occur on the next day (the 1st)'s "03:00 am (Hong
# Kong Time 04:00 am)" and the clock will fall back for a half hour. (03:00
# probably refer to the time commonly used in mainland China at the time given
# the paper's background) ... the sunrise/sunset time given by South China
# Morning Post for October 1st was indeed moved by half an hour compares to
# before. After that, in December, the battle to capture Hong Kong started and
# the library doesn't seems to have any record stored about press during that
# period of time. Some media resumed publication soon after that within the
# same month, but there were not much information about time there. Later they
# started including a radio program guide when they restored radio service,
# explicitly mentioning it use Tokyo standard time, and later added a note
# saying it's half an hour ahead of the old Hong Kong standard time, and it
# also seems to indicate that Hong Kong was not using GMT+8 when it was
# captured by Japan.

# British astronomer Henry Park Hollis disliked India Standard Time's offset:
# "A new time system has been proposed for India, Further India, and Burmah.
# The scheme suggested is that the times of the meridians 5½ and 6½ hours

# I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates,
# stopping after 2037 when 32-bit time_t's overflow.
# That cal-persia used Birashk's approximation, which disagrees with the solar

# I used the following code in GNU Emacs 26.1 to generate the "Rule Iran"

#
# 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

# 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.

# "Lacking enough votes, the city faction tries to filibuster until time runs
