+# started including a radio program guide when they restored radio service,
+# explicitly mentioning it use Tokyo standard time, and later added a note

+#
+# Japan invaded those islands in 1914, and records shows that they were

+#
+# 1915 January telecommunication record on the Jaluit Atoll shows they use

+# 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

+# * 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.

+# 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.
