About Gulf Standard Time (GST)
Gulf Standard Time (GST, IANA: Asia/Dubai, Asia/Muscat) is the civil time of the Arabian Gulf states, set at UTC+4:00 year-round (no DST). GST serves approximately 60 million people across: United Arab Emirates (UAE), Oman, Azerbaijan, Armenia, Georgia (most), Mauritius, Réunion (French territory), Seychelles, Russia's Samara Time region. The 'Gulf Standard Time' specifically refers to UAE + Oman in regional aviation/business usage. GST shares the same UTC offset as Mauritius Time (MUT), Armenia Time (AMT), Azerbaijan Time (AZT), Georgia Time (GET), and is +1 hour ahead of Moscow / Saudi Arabia. Major GST cities: Dubai (3.5M city, 4.8M metro — UAE + global trade hub), Abu Dhabi (1.5M city, 2.9M metro — UAE capital), Sharjah (1.7M), Muscat Oman (1.7M metro — capital), Salalah Oman (370K), Baku Azerbaijan (2.3M), Yerevan Armenia (1.1M), Tbilisi Georgia (1.2M). Affects: DFM (Dubai Financial Market) + ADX (Abu Dhabi Securities Exchange) trading hours, Emirates Airlines / Etihad Airways hub-operations scheduling, Hajj/Umrah pilgrimage timings for travelers transiting Dubai, Dubai Expo + Burj Khalifa fountain shows + Dubai Mall operating hours.
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.
