Regional context

Timezones across East Asia

East Asia — China, Japan, Korea, Taiwan, Mongolia — sits mostly at UTC+8 (China's single-timezone policy across the whole country) or UTC+9 (Japan, Korea). None observe DST anymore (Japan ended its post-WW2 experiment in the 1950s), so offsets are fixed. The region's single-large-zone footprint makes cross-Asia coordination unusually easy compared to Europe or North America.
