True... 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?
