Why people convert WAT to Honolulu time

Scheduling a call from WAT to Honolulu: a 10:00 AM start in WAT lands at 11:00 PM in Honolulu the previous day, so you can confirm the slot without doing the arithmetic yourself.
Handling a -11h gap: WAT 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 10:00 PM in WAT.
Coordinating a WAT-based team with Honolulu 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 WAT" is unambiguous; "3 PM" across a -11h gap is not.
With a -11h gap there is no shared 9-to-5 window, so alternate the early start: one week WAT takes the early slot, the next week Honolulu does.
