Why people convert Zurich to HST time

Scheduling a call from Zurich to HST: a 10:00 AM start in Zurich lands at 10:00 PM in HST the previous day, so you can confirm the slot without doing the arithmetic yourself.
Handling a -12h gap: Zurich and HST 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 HST is 9:00 PM in Zurich.
Keeping family and friends in sync: knowing that 8:00 PM in Zurich is 8:00 AM in HST makes it easy to avoid calling at 3 AM.

Always state the zone abbreviation, not just the hour. "3:00 PM CEST" is unambiguous; "3 PM" across a -12h gap is not.
With a -12h gap there is no shared 9-to-5 window, so alternate the early start: one week Zurich takes the early slot, the next week HST does.
