A note on CST (China): it can also mean the abbreviation CST is shared with US Central Time and Cuba Standard Time.

Hawaii Standard Time (HST) is used in all of Hawaii, which does not observe daylight saving

China Standard Time (CST) is used in the whole of China, which runs on one offset from Kashgar to Shanghai
