Why people convert Santiago to WIB time

Scheduling a call from Santiago to WIB: a 10:00 AM start in Santiago lands at 8:00 PM in WIB, so you can confirm the slot without doing the arithmetic yourself.
Handling a +10h gap: Santiago and WIB 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 WIB is 7:00 PM in Santiago.
Keeping family and friends in sync: knowing that 8:00 PM in Santiago is 6:00 AM in WIB makes it easy to avoid calling at 3 AM.

Always state the zone abbreviation, not just the hour. "3:00 PM CLST" is unambiguous; "3 PM" across a +10h gap is not.

It covers Java, Sumatra, West Kalimantan and the provinces around them — home to Jakarta, the country's capital and largest city, plus Surabaya and Bandung.

WIB shares its UTC+07:00 offset with Indochina Time (ICT) and Christmas Island Time, but is a distinct zone covering the western half of the Indonesian archipelago. The country's other zones are WITA (UTC+08:00) in the centre and WIT (UTC+09:00) in the east.

Business hours overlap
