ハイライト

It addresses an issue that might affect some types of Secure Sockets Layer (SSL) and Transport Layer Security (TLS) connections. These connections might have handshake failures. For developers, the affected connections are likely to receive one or more records followed by a partial record with a size of less than 5 bytes within a single input buffer. If the connection fails, your app will receive the error, “SEC_E_ILLEGAL_MESSAGE”.

既知の不具合

Applies to	Symptom	Workaround
IT admins	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: Clocks will not be advanced by an hour at 12:00 a.m. on October 28, 2022 for the Jordan time zone. 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.	This issue is addressed in KB5018483. This update will not install automatically. To apply this update, you can check for updates and select the optional preview to download and install. If you cannot install this update, you can mitigate this issue on devices in Jordan by doing either of the following on October 28, 2022: 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”. Important: We recommend using ONLY the above workaround to mitigate the issue with time created by the new Daylight Savings Time in Jordan. We do NOT recommend using any other workaround, as they can create inconsistent results and might create serious issues if done incorrectly.
