Why people convert WIB to Vietnam time

Scheduling a call from WIB to Vietnam: a 10:00 AM start in WIB lands at 10:00 AM in Vietnam, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both WIB and Vietnam are inside the 9-to-5 working day between 9:00 AM and 5:00 PM WIB time (9:00 AM–5:00 PM ICT). That is roughly 8 hours of usable overlap.
Booking travel or deliveries: tracking Vietnam local time against WIB keeps pickup windows and arrival estimates honest across the +0h offset.

Block 9:00 AM–5:00 PM WIB as the recurring meeting window if you work primarily from WIB and need Vietnam colleagues present.
