Andean Region Time Zones
Peru, Colombia, Chile, Argentina, Bolivia — South American Andes offsets.
Andean countries span multiple offsets: **Peru, Colombia, Ecuador** often **UTC-5**; **Chile** (America/Santiago) and **Argentina** (America/Argentina/Buenos_Aires) use **UTC-3/-4** with possible DST; **Bolivia** (America/La_Paz) is fixed **UTC-4**. Work with Brazil Time Zones Guide partners using named cities—not generic "South America time."
