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).

About Australian Eastern Standard Time (AEST)
Australian Eastern Standard Time (AEST, IANA: Australia/Sydney) is the civil time of Australia's most populous eastern states — New South Wales (NSW), Victoria (VIC), Queensland (QLD), Tasmania (TAS), Australian Capital Territory (ACT) — set at UTC+10:00. AEST is observed in winter; NSW + VIC + TAS + ACT switch to Australian Eastern Daylight Time (AEDT = UTC+11) from the first Sunday of October to the first Sunday of April. Queensland does NOT observe DST (stays on AEST year-round) — a state-level decision affirmed by referendums in 1992. AEST serves approximately 21 million Australians — about 80% of the country's population. AEST is identical in offset to Vladivostok Time (Russia), Papua New Guinea Time (PGT), Guam-Chamorro Time (CHST), and the US-territory Northern Mariana Islands. Major AEST cities: Sydney NSW (5.4M metro — largest Australian city + ASX home), Melbourne VIC (5.1M metro — 2nd-largest), Brisbane QLD (2.6M metro — 3rd-largest, on AEST year-round), Gold Coast QLD (725K — tourist coastline), Newcastle NSW (475K), Canberra ACT (450K — federal capital), Hobart TAS (250K — Tasmanian capital). Affects: ASX trading hours 10:00-16:00 AEST, Australian Cricket / AFL game scheduling, Great Barrier Reef + Sydney Opera House tourism operating hours.
