Microsoft has published a message for Chilean users that the upcoming time change will break certain features in Windows 7-11 both client and server versions. This is caused by the upcoming Daylight Savings Time (DST) date change. The change was announced on August 9, 2022, that the country’s official time would advance one hour on September 10th instead of the normal September 4th. As a result, users may encounter the following issues.
- The time shown in Windows and apps will not be correct.
- Apps and cloud services that use date and time for integral functions, such as Microsoft Teams and Microsoft Outlook, notifications, and scheduling of meetings might be 60 minutes off.
- Automation using date and time, such as Scheduled tasks, might not run at the expected time.
- The timestamp on transactions, files, and logs will be 60 minutes off.
- Operations that rely on time-dependent protocols such as Kerberos might cause authentication failures when attempting to log on or access resources.
- Windows devices and apps outside of Chile might also be affected if they are connecting to servers or devices in Chile or if they are scheduling or attending meetings taking place in Chile from another location or time zone. Windows devices outside of Chile should not use the workaround, as it would change their local time on the device.
Customers have a few options to work around the issue. They can apply these options on September 4th and undo them on September 11th.
- Select the Windows logo key, type “Date and time”, and select Date and time settings. From the Date & time settings page, toggle Adjust for daylight saving time automatically to Off.
- Go to Control Panel > Clock and Region > Date and Time > Change time zone and uncheck the option for “Automatically adjust clock for Daylight Saving Time”.
To mitigate this issue 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. This can be done by doing either of the following:
- Select the Windows logo key, type “Date and time”, and select Date and time settings. From the Date & time settings page, toggle Adjust for daylight saving time automatically to On.
- Go to Control Panel > Clock and Region > Date and Time > Change time zone and check the option for “Automatically adjust clock for Daylight Saving Time”.
Microsoft posted official documentation about the workaround but says, no other countries should need to make these changes and a patch will be released later this year once further testing is complete.
