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

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

+#
+# In January 1919 the occupying force issued a command that split the area

+# +2), and the command was to become effective from February 1 of the same

+# * 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

+# 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),

+# Another announcement issued in 1941 say that on April 1 that year,

+# 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

+#
+# After the end of WWII, in 1946 February, a document written by the
