Why people convert Colombia to CLT time

Scheduling a call from Colombia to CLT: a 10:00 AM start in Colombia lands at 11:00 AM in CLT, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Colombia and CLT are inside the 9-to-5 working day between 9:00 AM and 4:00 PM COT time (10:00 AM–5:00 PM CLT). That is roughly 7 hours of usable overlap.
Watching a live event or market open: Colombia viewers need 10:00 AM in CLT to catch a 9:00 AM start there, and 11:00 PM if the event is anchored to Colombia.

Always state the zone abbreviation, not just the hour. "3:00 PM COT" is unambiguous; "3 PM" across a +1h gap is not.
Block 9:00 AM–4:00 PM COT as the recurring meeting window if you work primarily from Colombia and need CLT colleagues present.
