About Australian Central Standard Time (ACST)
Australian Central Standard Time (ACST, IANA: Australia/Adelaide, Australia/Darwin) is the civil time of South Australia (SA) + Northern Territory (NT) + Broken Hill area of New South Wales, set at UTC+9:30 — one of the few 30-minute-offset time zones in the developed world. South Australia observes Daylight Saving Time per state legislation (switching to ACDT = UTC+10:30) from the first Sunday of October to the first Sunday of April, while Northern Territory does NOT observe DST (stays on ACST year-round). The 30-minute offset is preserved because central Australia's longitudinal position (135°E) falls between Australian Western Standard Time (AWST = UTC+8) and Australian Eastern Standard Time (AEST = UTC+10), and the colonial-era decision was to split the difference. ACST serves approximately 1.9 million Australians: 1.7M in SA + 250K in NT + 20K in Broken Hill NSW. Major ACST cities: Adelaide (1.4M metro — South Australia capital), Darwin (150K — Northern Territory capital and the gateway to Asia from northern Australia), Alice Springs (25K — center of Australian Outback tourism + Uluru-Kata Tjuta National Park access), Mount Gambier (30K), Whyalla (22K), Broken Hill NSW (18K). Affects: ASX-South-Australian-listed mining-company operations, Darwin port shipping to Indonesia + Timor-Leste.
About Indochina Time (ICT)
Indochina Time (ICT, IANA: Asia/Bangkok, Asia/Ho_Chi_Minh) is the civil time of mainland Southeast Asia (excluding Myanmar + Indonesia), set at UTC+7:00 year-round (no DST). ICT serves approximately 250 million people across: Thailand, Vietnam, Cambodia, Laos, Christmas Island (Australian territory in Indian Ocean), Java + Sumatra + western Indonesia (which uses Western Indonesian Time WIB = identical UTC+7 offset). ICT shares its offset with Krasnoyarsk Time (Russia, UTC+7) and Davis Antarctica research station. Major ICT cities: Bangkok Thailand (10.7M metro — Southeast Asia's largest tourist destination + ASEAN economic hub), Ho Chi Minh City Vietnam (10M city, 14M metro — formerly Saigon, Vietnam's largest city), Hanoi Vietnam (8M metro — capital), Jakarta Indonesia (10.5M city, 35M metro — uses WIB which is identical to ICT but a different zone-name), Phnom Penh Cambodia (2M), Vientiane Laos (820K). Affects: SET (Stock Exchange of Thailand) trading hours, HOSE + HNX (Vietnam stock exchanges) trading, Phnom Penh Securities Exchange (CSX) hours, Bangkok BTS Skytrain + MRT subway operating hours, and ASEAN diplomatic-meeting schedules.
