Why people convert Seoul to Lagos time

Scheduling a call from Seoul to Lagos: a 10:00 AM start in Seoul lands at 2:00 AM in Lagos, so you can confirm the slot without doing the arithmetic yourself.
Handling a -8h gap: Seoul and Lagos 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 Lagos is 1:00 AM in Seoul.
Watching a live event or market open: Seoul viewers need 1:00 AM in Lagos to catch a 9:00 AM start there, and 8:00 AM if the event is anchored to Seoul.

Always state the zone abbreviation, not just the hour. "3:00 PM KST" is unambiguous; "3 PM" across a -8h gap is not.
With a -8h gap there is no shared 9-to-5 window, so alternate the early start: one week Seoul takes the early slot, the next week Lagos does.
