Why people convert Tehran to Kuala Lumpur time

Scheduling a call from Tehran to Kuala Lumpur: a 10:00 AM start in Tehran lands at 2:30 PM in Kuala Lumpur, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Tehran and Kuala Lumpur are inside the 9-to-5 working day between 9:00 AM and 12:30 PM IRST time (1:30 PM–5:00 PM MYT). That is roughly 3 hours 30 minutes of usable overlap.
Watching a live event or market open: Tehran viewers need 1:30 PM in Kuala Lumpur to catch a 9:00 AM start there, and 7:30 PM if the event is anchored to Tehran.

Always state the zone abbreviation, not just the hour. "3:00 PM IRST" is unambiguous; "3 PM" across a +4h 30m gap is not.
Block 9:00 AM–12:30 PM IRST as the recurring meeting window if you work primarily from Tehran and need Kuala Lumpur colleagues present.
