Actually I wonder how I have to read the zic files in this case. It says: Rule Japan 1948 only - May Sun>=1 2:00 1:00 D Rule Japan 1948 1951 - Sep Sat>=8 2:00 0 S Rule Japan 1949 only - Apr Sun>=1 2:00 1:00 D Rule Japan 1950 1951 - May Sun>=1 2:00 1:00 D Zone Asia/Tokyo 9:18:59 - LMT 1887 Dec 31 15:00u 9:00 - JST 1896 9:00 - CJT 1938 9:00 Japan J%sT The last column of the rules tell us what to put in for %s, but why is there no Rule Japan 19xx max .... S rule? I.e. a rule saying that after some date we should always replace %s by S? What am I missing here?
