- Coordinating a Perth-based team with Anchorage contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM AWST" is unambiguous; "3 PM" across a -16h gap is not.
- With a -16h gap there is no shared 9-to-5 window, so alternate the early start: one week Perth takes the early slot, the next week Anchorage does.
