Why people convert COT to Dubai time

Scheduling a call from COT to Dubai: a 10:00 AM start in COT lands at 7:00 PM in Dubai, so you can confirm the slot without doing the arithmetic yourself.
Handling a +9h gap: COT and Dubai 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 Dubai is 6:00 PM in COT.
Booking travel or deliveries: tracking Dubai local time against COT keeps pickup windows and arrival estimates honest across the +9h offset.

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