- Handling a +14h gap: AST 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 11:00 PM in AST.
- Watching a live event or market open: AST viewers need 11:00 PM in Melbourne to catch a 9:00 AM start there, and 10:00 AM if the event is anchored to AST.
- Always state the zone abbreviation, not just the hour. "3:00 PM AST" is unambiguous; "3 PM" across a +14h gap is not.
- With a +14h gap there is no shared 9-to-5 window, so alternate the early start: one week AST takes the early slot, the next week Melbourne does.
