   Just a minor correction:

   I think you mean the signing of the peace treaty with Japan, online at
[assets.documentcloud.org/documents/1338718/san-francisco-peace-treaty-1951.pdf].
   This happened on 1951-09-08 (a Saturday) in San Francisco, as stated in
   the text. It is quite likely that it was done after 08:00 PPT, so that
   local time in Tokyo was after 1951-09-09T00:00 in either interpretation,
   and not three days before the switch to winter time.
   US occupation of Japan ended only in 1952.
