- Scheduling a call from Denver to Nairobi: a 10:00 AM start in Denver lands at 7:00 PM in Nairobi, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +9h gap: Denver and Nairobi 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 Nairobi is 6:00 PM in Denver.
- Coordinating a Denver-based team with Nairobi 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 MDT" is unambiguous; "3 PM" across a +9h gap is not.
