PST vs NZST — cities and working rhythm
US West Coast — home of Silicon Valley, LA entertainment, and the SaaS / VC ecosystem. Business hours 9 AM – 6 PM PT. Startup / tech culture stretches later than East Coast: it's common for calendar invites from West Coast product teams to run through 8 PM PT.
New Zealand winter offset (April to September), UTC+12 — one of the earliest zones to open the world business day. NZ summer flips to NZDT (UTC+13). 3-4 h ahead of Sydney seasonally.
Time gap: NZST is 20.0 hours ahead of PST (standard-time offsets — daylight-saving flips shift this by an hour twice a year in most northern-hemisphere zones).
