Why people convert HKT to Colombia time

Scheduling a call from HKT to Colombia: a 10:00 AM start in HKT lands at 9:00 PM in Colombia the previous day, so you can confirm the slot without doing the arithmetic yourself.
Handling a -13h gap: HKT and Colombia 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 Colombia is 8:00 PM in HKT.
Watching a live event or market open: HKT viewers need 8:00 PM in Colombia to catch a 9:00 AM start there, and 1:00 PM if the event is anchored to HKT.

Always state the zone abbreviation, not just the hour. "3:00 PM HKT" is unambiguous; "3 PM" across a -13h gap is not.
With a -13h gap there is no shared 9-to-5 window, so alternate the early start: one week HKT takes the early slot, the next week Colombia does.
