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). Affects: IDX (Indonesia Stock Exchange) trading hours, Jakarta KRL commuter-rail schedules, Borobudur Buddhist temple + Prambanan Hindu temple tourism schedules.
About Alaska Standard Time (AKST)
Alaska Standard Time (AKST, IANA: America/Anchorage and America/Juneau) is the time zone for most of the State of Alaska, set at UTC-9:00. AKST is observed from the first Sunday in November to the second Sunday in March per the Uniform Time Act of 1966 + Energy Policy Act of 2005; Alaska switches to Alaska Daylight Time (AKDT = UTC-8:00) for the remainder of the year. The vast Alaska time zone covers ~3,200 km east-to-west — from Ketchikan to Atka in the Aleutians — and is the only US time zone that spans more than 1,000 miles longitudinally, meaning solar-noon in different Alaska cities varies by over an hour from local clock time. Major population centers: Anchorage (~290,000), Fairbanks (~95,000), Juneau state capital (~32,000). Used in coordination of cruise-ship schedules through the Inside Passage, North Slope oil-pipeline operations, US Air Force JBER and Eielson AFB activities, and Alaska commercial fishing season openings managed by ADF&G.
