Why people convert Santiago to UTC time

Scheduling a call from Santiago to UTC: a 10:00 AM start in Santiago lands at 1:00 PM in UTC, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Santiago and UTC are inside the 9-to-5 working day between 9:00 AM and 2:00 PM CLST time (12:00 PM–5:00 PM UTC). That is roughly 5 hours of usable overlap.
Watching a live event or market open: Santiago viewers need 12:00 PM in UTC to catch a 9:00 AM start there, and 9:00 PM if the event is anchored to Santiago.

Always state the zone abbreviation, not just the hour. "3:00 PM CLST" is unambiguous; "3 PM" across a +3h gap is not.
Block 9:00 AM–2:00 PM CLST as the recurring meeting window if you work primarily from Santiago and need UTC colleagues present.
Santiago: Clocks fall back on Sun, Apr 4, 2027. Re-check this page after that date because the offset changes and so does the +3h gap.

It is effectively the successor to GMT and is based on International Atomic Time with leap seconds added to keep it synchronized with Earth's rotation. UTC is used in aviation, computing, navigation, weather forecasting, and the International Space Station. Most programming languages and databases store timestamps in UTC.
