- Handling a -10h gap: Riyadh and Vancouver 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 Vancouver is 11:00 PM in Riyadh.

- Always state the zone abbreviation, not just the hour. "3:00 PM AST" is unambiguous; "3 PM" across a -10h gap is not.
- With a -10h gap there is no shared 9-to-5 window, so alternate the early start: one week Riyadh takes the early slot, the next week Vancouver does.
