Editor’s Note: 12.26.2023: We have updated this post to clarify the DST dates and what happens if the recommended updates are not installed.

 

In the month of May 2023, our internal Customer Support team reported an error, which was affecting Daylight Saving Time (DST) in Israel for events that were scheduled for March 2024 and onwards. This was resulting in the meeting times in Israel being off by one hour. On further investigation, it was realized that it was happening due to a missing registry in one of the internal systems.  

 

To ensure that this issue is proactively resolved, Microsoft released the Windows updates listed below to account for the correct DST changes:

  • Daylight Saving Time in Israel will start on Friday, March 29, 2024 at 2:00:00 AM local standard time. 
    • The clocks will be turned forward one hour to 3:00:00 AM local daylight time.
  • Daylight Saving Time in Israel will end on Sunday, October 27, 2024 at 2:00:00 AM local daylight time.
    • The clocks will be turned backward one hour to 1:00:00 AM local standard time.

 

This change is available in the August 2023 Cumulative Update preview released on August 22, 2023, for the 20H2 and the newer versions of Windows 10 and 11. All other supported Windows versions received the update as part of the September 2023 monthly quality update scheduled to release on September 12, 2023.

 

Note: If you don’t install these Windows updates released in August 2023 and September 2023, you will not see the correct time change schedule.

 

All Windows updates containing this fix have the following release note text:

    AshishNawal can you clarify what happens if this patch is not applied? Does it only affect users during the time (already passed) between Mar 22 and Mar 29? Or does it impact future transitions, too?

    in your case Date:(M:3 D:4 DoW:5) represents the following 

    M:3 = March  

    D:4 = Week 4

    Dow:5 = Day of week 5

    Clearly Microsoft has a bug!

    1. in: https://www.gov.il/BlobFolder/reports/alert_1723/he/ALERT-CERT-IL-W-1723.pdf
    it state that expected:
    w32tm /tz
    Time zone: Current:TIME_ZONE_ID_DAYLIGHT Bias: -120min (UTC=LocalTime+Bias)
    [Standard Name:"Jerusalem Standard Time" Bias:0min Date:(M:10 D:5 DoW:0)]
    [Daylight Name:"Jerusalem Daylight Time" Bias:-60min Date:(M:3 D:4 DoW:5)]

    ==> Meaning the summer time started already in 4/March. Yet summer time starts only 29 March.
    So between 4 - 29/March we have (had) wrong time (offset by 1 hour).  Thanks Microsoft!

    The same issue is happening here, where 99 percent of the workstations are working fine, but some Windows 11 23H2 workstations are not. There is a one hour difference between the working and non-working workstations.

    All workstations have been patched.

    I tried copying the registry key from a working workstation to the issue workstation, but it gets overwritten.

    UPDATE: It was my fault, I didn't scroll to the bottom of the:https://www.gov.il/BlobFolder/reports/alert_1723/he/ALERT-CERT-IL-W-1723.pdf

    For anyone looking, export: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Time Zones\Israel Standard Time

    from a working computer and Import to the non working one.

    Just want to update with official information from the Israeli Cyber - https://www.gov.il/BlobFolder/reports/alert_1723/he/ALERT-CERT-IL-W-1723.pdf

     

    It includes a procedure for getting the updated daylight savings time and export it for other systems - Of course, it does not mean that you should not install the updates

    what about the years after 2024 ?

    i don't see any updates for the next years at the Registry "Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Time Zones\Israel Standard Time\Dynamic DST"

     

    why you didn't build an updated for the next 10 years as you did in 2004 ?

     

    Thank you.

    Hey orbiton 

    Thank you for your replay.

    For each supported operating system, including those with Extended Security Updates (ESU), an update has been released to address the DST date issue. If you're referring to "servers that cannot be updated", specifically Windows Server 2008, it is necessary to have ESU installed on the server before applying the KB update. Otherwise, the recommended course of action is to upgrade the server.

    Regarding requests for "registry instructions," official registry instructions are not provided. Our recommended and official method is to install the KB update.
    If you encounter specific issues, it is advised to open a support ticket for further assistance.
