New time zone update database has been published pushing back Chile's 2022 DST time change from 09/04 to 09/11 Description A new IANA time zone database update has been released (2022b). Per the IANA website the "Time Zone Database (often called tz or zoneinfo ) contains code and data that represent the history of local time for many representative locations around the globe. It is updated periodically to reflect changes made by political bodies to time zone boundaries, UTC offsets, and daylight-saving rules."

The time zone database is implemented by Java to maintain timezone and offset data. This time zone database is maintained within the Java Development Kit (JDK).

The latest update contains an impactful change where Chile's 2022 Daylight Saving Time (DST) start is delayed from September 4 to September 11. This was a recent update released by Chile's ministry of the interior.
