1736 # In January 1919 the occupying force issued a command that split the area |
|
1737 # into three different timezone with meridian of 135E, 150E, 165E (JST+0, +1, |
|
1738 # +2), and the command was to become effective from February 1 of the same |
|
1739 # year. Despite the target of the command is still only for the occupying |
|
1740 # force itself, further publication have described the time as the standard |
|
1741 # time for the occupied area and thus it can probably be seen as such. |
|
1742 # * Area that use meridian of 135E: Palau and Yap civil administration area |
|
1743 # (Southern Islands Western Standard Time) |
|
1744 # * Area that use meridian of 150E: Truk (Chuuk) and Saipan civil |
|
1745 # administration area (Southern Islands Central Standard Time) |
|
1746 # * Area that use meridian of 165E: Ponape (Pohnpei) and Jaluit civil |
|
1747 # administration area (Southern Islands Eastern Standard Time). |
|
1748 # * In the next few years Japanese occupation of those islands have been |
|
1749 # formalized via League of Nation Mandate (South Pacific Mandate) and formal |
|
1750 # governance structure have been established, these district [become |
|
1751 # subprefectures] and timezone classification have been inherited as standard |
|
1752 # time of the area. |
|
1753 # * Saipan subprefecture include Mariana islands (exclude Guam which was |
|
1754 # occupied by America at the time), Palau and Yap subprefecture rule the |
|
1755 # Western Caroline Islands with 137E longitude as border, Truk and Ponape |
|
1756 # subprefecture rule the Eastern Caroline Islands with 154E as border, Ponape |
|
1757 # subprefecture also rule part of Marshall Islands to the west of 164E |
|
1758 # starting from (1918?) and Jaluit subprefecture rule the rest of the |
|
1759 # Marshall Islands. |
|
1760 # |
|
1761 # And then in year 1937, an announcement was made to change the time in the |
|
1762 # area into 2 timezones: |
|
1763 # * Area that use meridian of 135E: area administered by Palau, Yap and |
|
1764 # Saipan subprefecture (Southern Islands Western Standard Time) |
|
1765 # * Area that use meridian of 150E: area administered by Truk (Chuuk), |
|
1766 # Ponape (Pohnpei) and Jaluit subprefecture (Southern Islands Eastern |
|
1767 # Standard Time) |
|
1768 # |
|
1769 # Another announcement issued in 1941 say that on April 1 that year, |
|
1770 # standard time of the Southern Islands would be changed to use the meridian |
|
1771 # of 135E (GMT+9), and thus abolishing timezone different within the area. |
|
1772 # |
|
1773 # Then Pacific theater of WWII started and Japan slowly lose control on the |
|
1774 # island. The webpage I linked above contain no information during this |
|
1775 # period of time.... |
|
1776 # |
|
1777 # After the end of WWII, in 1946 February, a document written by the |
|
1778 # (former?) Japanese military personnel describe there are 3 hours time |
|
1779 # different between Caroline islands time/Wake island time and the Chungking |
|
1780 # time, which would mean the time being used there at the time was GMT+10. |
|
1781 # |
|
1782 # After that, the area become Trust Territories of the Pacific Islands |
|
1783 # under American administration from year 1947. The site listed some |
|
1784 # American/International books/maps/publications about time used in those |
|
1785 # area during this period of time but they doesn't seems to be reliable |
|
1786 # information so it would be the best if someone know where can more reliable |
|
1787 # information can be found. |

1792 # For the above, use vague dates like "1914" and "1945" for transitions that |
|
1793 # plausibly exist but for which the details are not known. The information |
|
1794 # for Wake is too sketchy to act on. |
|
1795 # |
|
1796 # The 1906 GMT+10 info about German-controlled islands might not have been |
|
1797 # done, so omit it from the data for now. |
