I'd have to dig to try to find out what the date on this would be.

Russia is telling since they changed their timezones in 2016. I'm going to note that timezones are also a political identity too. https://www.timeanddate.com/news/time/russia-new-time-zones....

China is aligned with Beijing and the rest of the country follows from when noon in Beijing is.

Sudan's history is in https://en.wikipedia.org/wiki/Time_in_Sudan

Argentina is https://en.wikipedia.org/wiki/Time_in_Argentina - My speculation would be that Argentina (the east coast especially) wanted to be economically synchronized with the coastal cities of eastern Brazil. Buenos Aires and São Paulo being on the same timezone makes it easier for the two of them to do business.

Alaska used to have four timezones. In 1983, they were consolidated into two timezones - Aleutian and Alaska. Being in -9 rather than -10 brings Anchorage closer to the Pacific west coast in its business day with the note that it doesn't matter too much when solar noon is if sun is up for 22 hours or 5 hours.
