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 Western Standard Time (AWST)
Australian Western Standard Time (AWST, IANA: Australia/Perth) is the civil time of Western Australia (WA), set at UTC+8:00 year-round (no DST). Western Australia has rejected Daylight Saving Time in four separate referendums (1975, 1984, 1992, 2009 — each time defeated), so AWST is observed without seasonal change despite the rest of Australia (eastern states) observing AEDT in summer. The unusual situation creates a 3-hour offset between Perth (AWST = UTC+8) and Sydney (AEDT = UTC+11) in summer, vs. the standard 2-hour offset in winter (AWST UTC+8 vs AEST UTC+10). AWST is identical in offset to China Standard Time (CST), Singapore Time (SGT), Hong Kong Time (HKT), Philippine Time (PHT), Malaysia Time (MYT). AWST serves approximately 2.8 million Western Australian residents — the world's largest sub-national area on a single time zone (WA is 2.527 million km² = larger than Western Europe). Major AWST cities: Perth (2.1M metro — Australia's 4th-largest city), Mandurah (95K), Bunbury (75K), Geraldton (40K), Kalgoorlie-Boulder (30K — gold mining hub), Albany (35K — historic whaling port), Broome (15K — pearl industry + tourism), Karratha (15K — Pilbara iron-ore export hub). Affects: ASX (Australian Securities Exchange) operations from Perth offices, Rio Tinto / BHP Pilbara iron-ore shipping coordination.
