Why people convert Zurich to Honolulu time

Handling a -12h gap: Zurich and Honolulu 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 Honolulu is 9:00 PM in Zurich.
Watching a live event or market open: Zurich viewers need 9:00 PM in Honolulu to catch a 9:00 AM start there, and 12:00 PM if the event is anchored to Zurich.

Always state the zone abbreviation, not just the hour. "3:00 PM CEST" is unambiguous; "3 PM" across a -12h gap is not.
