On August 8, 2022, the Chilean government made an official announcement about a Daylight Saving Time (DST) time zone change. Starting at 12:00 a.m. Saturday, September 10, 2022 until 12:00 a.m. Saturday, April 1, 2023, the official time will advance 60 minutes.
The impacts of this change are as follows:
Microsoft plans to release an update to support this change; however, there may be insufficient time to properly build, test, and release such an update before the change goes into effect. In the meantime, we recommend that organizations with devices in the Republic of Chile temporarily disable automatic DST adjustments in Windows to reflect the correct local time between September 4, 2022 and September 11, 2022.
This can be done in one of the two ways:
For those in the Santiago time zone, after 12:00 a.m. on September 11, 2022, and for those in the Easter Islands time zone, after 10:00 p.m. on September 10, 2022, follow the steps below to re-enable automatic DST adjustments and ensure accurate time switching with future DST transitions.
For Microsoft's official policy on DST and time zone changes, please see Daylight saving time help and support. For information on how to update Windows to use the latest global time zone rules, see How to configure daylight saving time for Microsoft Windows operating systems.
