- Handling a -10h gap: WIB and São Paulo 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 São Paulo is 11:00 PM in WIB.

About WIB (Western Indonesia Time)

The country's other zones are WITA (UTC+08:00) in the centre and WIT (UTC+09:00) in the east.

Brasilia Time (BRT) is the standard time in the most populous regions of Brazil, including São Paulo, Rio de Janeiro, and the capital Brasília. Brazil abolished daylight saving time in 2019, so BRT is now observed year-round in these regions. Brazil spans four time zones in total.
