On October 5, 2022, the Jordanian government made an official announcement ending the winter-time Daylight Saving Time (DST) time zone change. Starting at 12:00 a.m. Friday, October 28, 2022, the official time will not advance by an hour and will permanently shift to the UTC + 3 time zone. 

The impact of this change is as follows: 

1. Clocks will not be advanced by an hour at 12:00 a.m. on October 28, 2022 for the Jordan time zone.

2. The Jordan time zone will permanently shift to the UTC + 3 time zone.

Symptoms if no update is installed and the workaround is not used on devices in the Jordan time zone on October 28, 2022 or later:

• Time shown in Windows and apps will not be correct.

• Apps and cloud services which 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.

• 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 logon or access resources.

• Windows devices and apps outside of Jordan might also be affected if they are connecting to servers or devices in Jordan or if they are scheduling or attending meetings taking place in Jordan from another location or time zone. Windows devices outside of Jordan should not use the workaround, as it would change their local time on the device.
