SYMPTOMS

The start dates and the end dates for daylight saving time (DST) in many countries change from year to year. Additionally, some countries may change their DST recognition policy or may change the local time offset from Coordinated Universal Time (UTC). In this scenario, some schedules and some applications that depend on date and time calculations may have a problem.

CAUSE

This issue occurs because of incorrect or missing time zone information, which can occur if the latest Windows Daylight Saving Time Cumulative Update has not been applied.

RESOLUTION

To fix this problem, follow these steps.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base: 322756 How to back up and restore the registry in Windows
  1. Import the applicable TZI and annual rules into the registry under the following registry subkey:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Time Zones

    Note If registry value does not exist, import the English string into the registry under the following registry subkey for the "Non-MUI_*" string (for example: "Display", "Dlt", "Std" registry keys):
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Time Zones
  2. Run the appropriate command for your operating system:
    Windows XP and Windows Server 2003
    Tzchange.exe /w 2147483648

    Windows Vista, Windows 7, Windows Server 2008 and Windows Server 2008 R2
