Why people convert Santiago to SGT time

Scheduling a call from Santiago to SGT: a 10:00 AM start in Santiago lands at 9:00 PM in SGT, so you can confirm the slot without doing the arithmetic yourself.
Handling a +11h gap: Santiago and SGT 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 SGT is 8:00 PM in Santiago.
Booking travel or deliveries: tracking SGT local time against Santiago keeps pickup windows and arrival estimates honest across the +11h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM CLST" 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 Santiago takes the early slot, the next week SGT does.
