- Handling a -16h gap: Shanghai and PST 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 PST is 5:00 PM in Shanghai.
- Keeping family and friends in sync: knowing that 8:00 PM in Shanghai is 4:00 AM in PST makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM CST" is unambiguous; "3 PM" across a -16h gap is not.
