About Western Indonesian Time (WIB)
Western Indonesian Time (WIB — Waktu Indonesia Barat, IANA: Asia/Jakarta) is the civil time of western Indonesia, set at UTC+7:00 year-round (no DST). Indonesia spans 3 time zones (WIB UTC+7, WITA UTC+8, WIT UTC+9) covering its 17,508+ island archipelago across ~5,000 km of longitude — the world's largest archipelagic country by area. WIB serves approximately 200 million Indonesian people on Java, Sumatra, West Kalimantan, and Central Kalimantan — including the major population centers. WIB is identical in offset to Indochina Time (ICT) used by mainland Thailand/Vietnam/Cambodia/Laos. Major WIB cities: Jakarta (10.5M city, 35M metro — Indonesia's capital and Southeast Asia's largest metro after Tokyo/Delhi/Shanghai/Manila), Surabaya (2.9M city, 9.3M metro — East Java capital), Medan (2.4M — Sumatra), Bandung (2.5M — West Java), Bekasi (3M — Jakarta satellite city), Tangerang (2.4M — Jakarta satellite), Depok (2.4M — Jakarta satellite), Semarang (1.7M — Central Java), Palembang (1.7M — Sumatra).

Major MST cities: Denver, Phoenix, Salt Lake City, Albuquerque, El Paso, Tucson, Calgary, Edmonton. MST covers Colorado, Utah, Wyoming, Montana, Idaho (most), New Mexico, Arizona, parts of Texas + Mexico (Sonora). Population ~17 million in the time zone. Affects: NORAD Cheyenne Mountain operations, Denver Mile-High Stadium NFL game scheduling, Colorado ski-resort lift-operating hours, US Bureau of Land Management permit operations, and the Mormon Tabernacle Choir broadcast schedule from Salt Lake City.
