Why people convert Vancouver to IRST time

Scheduling a call from Vancouver to IRST: a 10:00 AM start in Vancouver lands at 8:30 PM in IRST, so you can confirm the slot without doing the arithmetic yourself.
Handling a +10h 30m gap: Vancouver and IRST 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 IRST is 7:30 PM in Vancouver.
Booking travel or deliveries: tracking IRST local time against Vancouver keeps pickup windows and arrival estimates honest across the +10h 30m offset.
