There is an error in the 'America/Santiago' timezone. The week between September 4th, 2022 and September 10th, 2022 should have the offset of -4.0, but it currently shows -3.0.
This error occurred due to the 2022 Chilean national plebiscite, which caused the government to postpone the scheduled time change by one week, from September 3rd to September 10th.

This change was committed on 9 August 2022:
