1583:   # 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).
