日占期间，上海的时区被改成了+9,和东京一致

Due to historical reasons, the timezone a region is in can be constantly changin
g, even disregarding DST. For example, below is the output in a runtime in Shanghai, where the timezone is UTC+08:00.

const shModernOffset = new Date("2022-01-27").getTimezoneOffset(); // -480
const shHistoricalOffset = new Date("1943-01-27").getTimezoneOffset(); // -540

This is because during the Sino-Japanese War when Shanghai was under Japanese control, the timezone was changed to UTC+09:00 to align with Japan's (in effect, it was a "year-round DST"), and this was recorded in the IANA database.

小日本当年没少从CN运东西回去，kill了多少人，更别提这timezone改动了

修改:z16166 FROM 114.241.227.*
FROM 114.241.227.*

2015年的时候，朝鲜说+9是“日帝国主义强加给我们的”而+8是“中国修正主义的”
所以他们选择+8.5
这段应该也被IANA记录下来了
