I also examined other data concerning Japan in tzdata1998i.
The patch at the bottom of this mail fixes the following points.
- Only one timezone JST is used everywhere in Japan.
- In tzdata1998i, the location of 'Tokyo' (+3542+13946) seems to be
around the University of Tokyo. However, 'Tokyo' usually stands
for the former location of Tokyo Astronomical Observatory:
E 139 44' 40".90 (9h 18m 58s.727), N 35 39' 16".0.
This data is from 'Rika Nenpyou (Chronological Scientific Tables) 1996'
edited by National Astronomical Observatory of Japan.
- JST (Japan Standard Time) has been used since Jan. 1, 1888
0:00AM (JST). The law is enacted on July 7, 1886.
I couldn't understand the comment 'There is no information for Marcus.'
Does anyone know what 'Marcus' is?
