Why people convert COT to Santiago time

Scheduling a call from COT to Santiago: a 10:00 AM start in COT lands at 12:00 PM in Santiago, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both COT and Santiago are inside the 9-to-5 working day between 9:00 AM and 3:00 PM COT time (11:00 AM–5:00 PM CLST). That is roughly 6 hours of usable overlap.
Coordinating a COT-based team with Santiago 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 COT" is unambiguous; "3 PM" across a +2h gap is not.
Block 9:00 AM–3:00 PM COT as the recurring meeting window if you work primarily from COT and need Santiago colleagues present.
