Why people convert Santiago to Vietnam time

Scheduling a call from Santiago to Vietnam: a 10:00 AM start in Santiago lands at 8:00 PM in Vietnam, so you can confirm the slot without doing the arithmetic yourself.
Handling a +10h gap: Santiago and Vietnam 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 Vietnam is 7:00 PM in Santiago.
Booking travel or deliveries: tracking Vietnam local time against Santiago keeps pickup windows and arrival estimates honest across the +10h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM CLST" is unambiguous; "3 PM" across a +10h gap is not.
With a +10h gap there is no shared 9-to-5 window, so alternate the early start: one week Santiago takes the early slot, the next week Vietnam does.
