About Pacific Daylight Time (PDT)
Pacific Daylight Time (PDT, IANA: America/Los_Angeles during DST window) is the summer-time variant of PST, set at UTC-7:00 — observed from the second Sunday in March to the first Sunday in November per the Energy Policy Act of 2005, which extended the US DST window by ~4 weeks compared to the prior Uniform Time Act of 1966 schedule. PDT is the same offset as Mountain Standard Time (MST), creating a confusing situation where Arizona (which doesn't observe DST and stays on MST year-round) shares the same clock as California during summer months but is one hour behind during winter. PDT is used by ~50 million people in California, Oregon, Washington, Nevada, British Columbia, Yukon, and Baja California Norte. Affects: West-Coast NYSE/Nasdaq market open shifts to 06:30 PDT, professional sports West Coast game-time broadcasts to East Coast PDT prime time, and US Pacific Fleet operations from Naval Base San Diego.
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.
