Why people convert PST to Melbourne time

- Handling a +18h gap: PST and Melbourne have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in Melbourne is 3:00 AM in PST.

- Always state the zone abbreviation, not just the hour. "3:00 PM PST" is unambiguous; "3 PM" across a +18h gap is not.
- With a +18h gap there is no shared 9-to-5 window, so alternate the early start: one week PST takes the early slot, the next week Melbourne does.
