Why people convert Ho Chi Minh to ART time

Scheduling a call from Ho Chi Minh to ART: a 10:00 AM start in Ho Chi Minh lands at 12:00 AM in ART, so you can confirm the slot without doing the arithmetic yourself.
Handling a -10h gap: Ho Chi Minh and ART 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 ART is 11:00 PM in Ho Chi Minh.
Coordinating a Ho Chi Minh-based team with ART 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 ICT" is unambiguous; "3 PM" across a -10h gap is not.
With a -10h gap there is no shared 9-to-5 window, so alternate the early start: one week Ho Chi Minh takes the early slot, the next week ART does.
