🌍 UTC (Coordinated Universal Time)
UTC is the primary time standard by which the world regulates clocks and time. It is not adjusted for Daylight Saving Time. UTC is used in aviation, computing, and international communications.
Related zones: GMT (Greenwich Mean Time), WET (Western European Time)
🇨🇳 CST (China Standard Time)
CST is UTC+8, covering all of China including Beijing, Shanghai, Hong Kong, and Macau. China does NOT observe Daylight Saving Time, so the offset remains constant year-round.

⚠️ Important Note
Unlike most countries, China uses a single time zone (UTC+8) for the entire country, including Xinjiang which is geographically in UTC+6. This means when it's noon in Beijing, it's also noon in western China.
