It was +# additionally complicated by the circumstances that, according to the 1940s +# Shanghai summer time essay cited in the database, some +# departments/businesses/people in the Shanghai city itself during that time +# period, refused to change their clock and instead only changed their opening +# hours. +# +# For example, as quoted in the article, in 1940, other than the authority +# itself, power, tram, bus companies, cinema, department stores, and other +# public service organizations have all decided to follow the summer time and +# spring forward the clock. On the other hand, the custom office refused to +# spring forward the clock because of worry on mechanical wear to the physical +# clock, postal office refused to spring forward because of disruption to +# business and log-keeping, although they did changed their office hour to +# match rest of the city.

It is said both time standards had their own supporters in the +# city at the time, those who prefer new time standard would have moved their +# clock while those who prefer the old time standard would keep their clock +# unchange, and there were different clocks that use different time standard +# in the city at the time for people who use different time standard to adjust +# their clock to their preferred time. +# +# a.

For the 1941 fall back, it was said that the fall back would occurs at +# the end of September (A newspaper headline cited by the essay, published on +# October 1, 1941, have the headlines which said "French Concession would +# rewind to the old clock this morning), but it ultimately didn't happen due +# to disagreement between the international settlement authority and the +# French concession authority, and the fall back ultimately occurred on +# November 1. +# +# e. In 1941 December, Japan have officially started war with the United +# States and the United Kingdom, and in Shanghai they have marched into the +# international settlement, taken over its control +# +# f.
